Product Description:FDA Food Grade FKM Fluororubber O-Ring Seals EPDMCommon food-grade seal materials are typically made from silicone rubber. For food-grade seals, ethylene propylene diene monomer (EPDM) rubber is generally used. A food-grade silicone seal with good tear resistance must meet two conditions: on the one hand, it refers to the high tear resistance of the silicone seal, and on the other hand, it means the seal can pass food-grade inspection standards. Therefore, silicone rubber products are often used in food pipeline sealing.The differences between tear-resistant food-grade silicone rubber seals and ordinary silicone seals are as follows:<img src="https://img-i-album.toocle.com/view/2022/02/27/69/621ad75bc3b69.png" style="max-width:100%;"/><img src="https://img-i-album.toocle.com/view/2022/02/27/55/621ad75be5e55.png" style="max-width:100%;"/>1. Ordinary silicone is not easy to stretch and tends to turn white, whereas tear-resistant silicone rubber seals do not turn white during stretching, have better elongation, and are not easy to break.2. Tear strength, crack resistance, and elongation are all better than ordinary silicone rubber.3. Compared to ordinary silicone rubber, transparency is much higher.4. Production costs are higher than ordinary silicone rubber, and environmental performance is better.Silicone rubber seal product characteristics include:1. Resistant to high and low temperature impact.2. Fast curing speed during operation.3. Extremely low odor; emissions during curing are harmless to humans.4. Bonds with multiple substrates without the need for primers.5. Good heat resistance, ozone resistance, and chemical resistance.6. Excellent electrical insulation properties.7. Complies with standard food-grade testing.FDA's authority over food, agricultural products, and seafood is managed by the Center for Food Safety and Applied Nutrition (CFSAN), which ensures that the U.S. food supply is safe, clean, fresh, and properly labeled. The center oversees $240 billion worth of food imports annually, including $15 billion in imported food. Key monitoring focuses include: 1. Food freshness; 2. Food additives; 3. Food biotin and other harmful ingredients; 4. Seafood safety analysis; 5. Food labeling; 6. Post-market tracking and alerts. According to the law passed by the U.S. Congress in 2003, foreign food enterprises must register with the FDA before exporting to the U.S. and provide shipment notifications to the FDA upon export.

Products primarily or entirely for human consumption.Large-size EPDM O-Ring Seals Large-dimension EPDM O-Rings EPDM Gasket Washer Characteristics:For resistance to chemical acid and alkali corrosion, fluororubber or EPDM O-ring seals are generally used. Simply put, the difference between the two is: fluororubber has better chemical resistance, higher temperature resistance (up to 250°C), while EPDM O-rings can only withstand up to 160°C. Fluororubber can resist oil media, whereas EPDM cannot. The advantage of EPDM is its lower cost, making it commonly used in sewage treatment or other water treatment products. EPDM is the English abbreviation for ethylene propylene diene monomer. The common color of EPDM is black, but it can be made in any color if you provide a color code or sample; Yongxin Company can produce it for you. The main chain of EPDM is a fully saturated linear structure without double bonds, with diene on the side chain, allowing vulcanization with sulfur. EPDM has excellent aging resistance, chemical resistance (e.g., strong alkalis, oxidizers, alcohols, acids), ozone resistance, weather resistance, and heat resistance (can be used long-term in 120°C environments), but it is not resistant to aliphatic and aromatic solvents. EPDM has a high filling characteristic in rubber due to its low density, but it lacks self-adhesion and mutual adhesion. Additionally, EPDM has outstanding steam resistance and can be used to make steam-resistant diaphragms and other sealing products. EPDM is widely used in components for televisions and washing machines, door and window seals, or various composite profile rubber strip production.The above provides information on the physical characteristics of EPDM O-rings. In addition, there are NBR rubber O-rings, VITON fluororubber O-rings, SIL silicone rubber O-rings, AEM butyl rubber O-rings, and other material O-ring seals.Rubber Material Description:Nitrile Rubber (NBR) Heat resistance 120°C, hardness around 70, black, good oil resistance.90-Degree Rubber (NBR) Same NBR material, higher hardness, better pressure resistance.Silicone Rubber (VMQ) Heat resistance 200°C, average oil resistance, none, good waterproofing (high-temperature silicone available, resistant up to 280°C).Fluororubber (FKM) Heat resistance 250°C, good oil resistance, corrosion resistance.EPDM Heat resistance 150°C, not oil-resistant, acid and alkali resistant.Hydrogenated Nitrile Rubber (HNBR) High-temperature resistance 130-180°C, low-temperature resistance -55 to -38°C.Common Materials: Nitrile Rubber (NBR), Fluororubber (VITON), EPDM, Silicone Rubber (VMQ), Chloroprene Rubber (CR), Styrene-Butadiene Rubber (SBR), Hydrogenated Nitrile Rubber (HNBR), and dozens of other rubber materials; products with Shore hardness 50–90 can be provided.EPDM Seals Eco-friendly Silicone O-Rings Fluororubber O-Rings Rubber Sealing Rings Waterproof Ring Size StandardsThe size of the O-ring affects the sealing effect and service life, so it is important to carefully select the appropriate size when choosing an O-ring. Consult our engineers to verify standard seal sizes based on your required working conditions.O-Rings Japanese Standard American Standard For Shafts For Holes Standard Specifications Complete Size Range,Custom rubber rings for various materials and special requirements.Under static conditions, O-ring seals prevent leakage of liquid and gas media.Under dynamic conditions, O-ring seals can also be used as dynamic sealing elements for axial reciprocating motion and low-speed rotation. more>

We sell various seals, hydraulic, pneumatic, and fluid control products and components. In terms of seals, Yongxin offers hydraulic and pneumatic sealing products, including dynamic seals, static seals, O-rings, oil seals, gaskets, packings, and more.EPDM Material Introduction:EPDM is a terpolymer of ethylene, propylene, and non-conjugated diene. Its main characteristics are superior resistance to oxidation, ozone, and corrosion. As part of the polyolefin family, EPDM has excellent chemical resistance. Among all rubbers, EPDM has the lowest specific gravity. It can absorb large amounts of fillers and oils without significantly affecting its properties, making it suitable for cost-effective rubber compounds. EPDM features outstanding aging resistance, electrical insulation, and ozone resistance. It can be heavily oil-extended and filled with carbon black, resulting in lower-cost products. Its chemical stability, wear resistance, elasticity, and oil resistance are comparable to styrene-butadiene rubber.EPDM is widely used in tire sidewalls, sealing strips, inner tubes, and automotive components.<img src="https://img-i-album.toocle.com/view/2022/04/06/df/624d4267363df.png" style="max-width:100%;"/>Product Characteristics:1. Aging Resistance: EPDM has excellent resistance to weather, ozone, heat, acids, alkalis, steam, color stability, electrical properties, oil extension, and fluidity at room temperature. EPDM products can be used long-term at 120°C and briefly or intermittently at 150-200°C. Suitable anti-aging agents can increase its service temperature. Peroxide-crosslinked EPDM can be used under harsh conditions. EPDM can withstand over 150 hours without cracking under 50 pphm ozone concentration and 30% elongation.2. Corrosion Resistance Rating Volume Swelling Rate/% Hardness Reduction Impact on Performance 1 lt;10<10 Slight or none. 2. 10-20<20 Minor 3. 30-60<30 Moderate. 4 60="">30 Severe3. Steam Resistance: EPDM has excellent steam resistance, even better than its heat resistance. After nearly 100 hours in 230°C superheated steam, its appearance remains unchanged. In contrast, fluororubber, silicone rubber, fluorosilicone rubber, butyl rubber, and natural rubber show significant deterioration under the same conditions in a shorter time.5. Hot Water Resistance: EPDM also performs well in hot water, but this is closely related to the vulcanization system. EPDM vulcanized with dicumyl peroxide and TMTD shows minimal change in mechanical properties and only 0.3% volume expansion after 15 months in 125°C superheated water.6. Electrical Properties: EPDM has excellent electrical insulation and corona resistance, outperforming styrene-butadiene rubber, chlorosulfonated polyethylene, polyethylene, and crosslinked polyethylene.7. Elasticity: Due to the absence of polar substituents in its molecular structure and low cohesive energy, EPDM maintains flexibility over a wide range, second only to natural rubber and polybutadiene rubber, and remains flexible at low temperatures.8. Adhesion: EPDM lacks active groups in its molecular structure and has low cohesive energy, making it prone to blooming and resulting in poor self-adhesion and mutual adhesion.Product Applications:Excellent weather resistance, ozone resistance, water resistance, and chemical resistance. Suitable for use with alcohols and ketones, as well as in high-temperature steam environments. Ideal for bathroom fixtures, automotive radiators, and brake systems. Not recommended for food applications or use with mineral oils. General temperature range: -55°C to 150°C.Advantages of O-rings:1. Suitable for various sealing forms: static seals, dynamic seals.2.

We sell various seals, hydraulic, pneumatic, and fluid control products and components. In terms of seals, Yongxin offers hydraulic and pneumatic sealing products, including dynamic seals, static seals, sealing rings, oil seals, gaskets, packing, etc.O-rings (also known as O-rings, O-rings, O-rings) are ring-shaped mechanical gaskets, which are ring-shaped elastomers with a circular cross-section. They are usually fixed in a groove and compressed by two or more components during assembly, thus creating a sealed interface. Because of their low price, simple manufacturing, reliable function, and simple installation requirements, O-rings are common mechanical designs for sealing. They can withstand pressures of tens of Pascals (thousands of pounds). O-rings can be used in static applications as well as in dynamic applications where there is relative movement between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.Rubber O-ring seals are mainly used to manufacture oil-resistant rubber products. The acrylonitrile content (%) in rubber O-ring seals is divided into five types: 42-46, 36-41, 31-35, 25-30, and 18-24. The higher the acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used in air at 120°C or in oil at 150°C for long periods. In addition, it has good water resistance, air tightness, and excellent bonding properties. It is widely used in the manufacture of various oil-resistant rubber products, various oil-resistant gaskets, spacers, sleeves, soft packaging, soft hoses, printing and dyeing rubber rollers, cable rubber materials, etc., and has become an elastic material in industries such as automotive, aviation, petroleum, and photocopying.<img src="https://img-i-album.toocle.com/view/2022/04/06/14/624d2ea903414.png" style="max-width:100%;"/>NBR rubber O-ring seals have excellent oil resistance. The typical NBR structure has about 78% trans configuration. Due to the presence of cyano groups in the molecular chain structure of NBR rubber O-ring seals, their oil resistance (such as resistance to mineral oil, liquid fuels, animal and vegetable oils, and solvents) is better than that of natural rubber, chloroprene rubber, and styrene-butadiene rubber. Compared with other rubbers, NBR has a wider range of use temperatures, with a long-term use temperature of 120°C. At the same time, NBR rubber O-ring seals have good low-temperature performance, with a glass transition temperature as low as -55°C.NBR rubber O-ring seals have good chemical stability and processing performance. As the acrylonitrile content in their structure increases, the relative density increases, the vulcanization speed accelerates, the tensile strength improves, but the rebound performance decreases, and the cold resistance deteriorates. Because the cyano groups in NBR rubber O-ring seals are easily polarized by electric fields, the dielectric properties decrease, making them semiconductor rubbers. NBR rubber O-ring seals can be divided into five categories based on ACN content: ultra-high, high, medium-high, medium, and low acrylonitrile. The production methods are divided into continuous and intermittent polymerization. Continuous polymerization is usually used for large-scale production with low consumption. Intermittent polymerization is suitable for multi-variety and small-batch production, with high engineering consumption.Although rubber has excellent physical and mechanical properties and processing performance, its long-term performance in acidic gasoline and high-temperature (150°C) environments is not as good as that of fluororubber and acrylate rubber. Therefore, hydrogenated rubber (HNBR) with excellent performance has been developed. In addition, rubber with extremely high cold resistance and high purity, as well as carboxylated rubber (XNBR), have also been developed.Rubber O-ring seals are light brown elastomers with a molecular weight of about 700,000. Due to the strong polar CN group, they have excellent stability against aliphatic hydrocarbon oils and gasoline. They are classified based on ACN content:High rubber: ACN content 36%-42%Medium-high rubber: ACN content 31%-35%Medium rubber: ACN content 25%-30%Low rubber: ACN content below 24%<img src="https://img-i-album.toocle.com/view/2022/04/06/32/624d2eba61732.png" style="max-width:100%;"/>Rubber O-ring seals have good heat resistance. Their heat resistance is better than that of natural rubber and styrene-butadiene rubber, with a long-term use temperature of up to 100°C, and they can be used at 120°C for 40 days. [1]① The ozone resistance of O-ring seals is worse than that of CR but better than NR.② O-ring seals are reinforced to give the rubber better physical and mechanical properties and wear resistance.③ When the acrylonitrile content of the rubber is 39%, the air tightness of O-ring seals is comparable to that of IIR rubber, and the air tightness is good.④ The low-temperature flexibility of O-ring seals is average.⑤ O-ring seals have excellent anti-static properties.⑥ O-ring seals have good plasticizing effects with polar esters.⑦ O-ring seals have good compatibility with polar substances, such as PVC, alkyd resins, and nylon.⑧ O-ring seals have low self-adhesion and generate more heat during the mixing process.Excellent Oil ResistanceRubber O-ring seals are one of the excellent rubbers with comprehensive properties such as oil resistance, physical and mechanical properties, and chemical resistance. Making full use of these characteristics can meet various applications. Among general-purpose rubbers, NBR rubber's resistance to benzene, petroleum-based oils, and non-polar solvents is far better than that of non-polar rubbers such as NR, SBR, and IIR, and also better than the polar CR. However, the performance of rubber in polar solvents and polar oils is not good enough.After-Sales Service:Yongxin Seals provides material certificates for all products, allowing customers to buy and use with confidence, without any worries!

Product Description:O-ring FDA certified food-grade rubber ring Suzhou sealing ring manufacturerSilicone rubber is divided into heat-curing type and room temperature curing type. Heat-curing types include methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, the most widely used with numerous product grades), methyl vinyl phenyl silicone rubber (PVMQ, resistant to low temperatures and radiation), as well as nitrile silicone rubber and fluorosilicone rubber, among others. MQ is a colorless, transparent, highly viscous, plastic linear polymer compound, with a backbone composed of silicon and oxygen atoms, and methyl groups attached to the silicon atoms. Its molecular weight ranges from 500,000 to 800,000. VMQ is a colorless, transparent, highly viscous, plastic linear polymer compound, with a backbone composed of silicon and oxygen atoms, and methyl and vinyl groups attached to the silicon atoms. Its molecular weight ranges from 500,000 to 800,000. PVMQ is obtained by introducing diphenyl siloxane segments or methylphenyl siloxane segments into the molecular chain of vinyl silicone rubber.<img src="https://img-i-album.toocle.com/view/2022/02/27/39/621aded5eca39.png" style="max-width:100%;"/><img src="https://img-i-album.toocle.com/view/2022/02/27/c1/621aded61d9c1.png" style="max-width:100%;"/><img src="https://img-i-album.toocle.com/view/2022/02/27/a8/621aded637fa8.png" style="max-width:100%;"/>000Temperature range: -60°C (special down to -115°C) to 204°C (special up to 260°C)O-ring material selection: Silicone rubberSilicone rubber refers to rubber whose backbone consists of alternating silicon and oxygen atoms, with silicon atoms typically bonded to two organic groups. Ordinary silicone rubber mainly consists of siloxane segments containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low-temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can enhance its temperature and oil resistance.Silicone rubber has good low-temperature resistance and can generally operate at -55°C. With the introduction of phenyl groups, it can withstand temperatures as low as -73°C. Silicone rubber also excels in heat resistance, operating long-term at 180°C and withstanding temperatures slightly above 200°C for several weeks or longer while retaining elasticity. It can momentarily endure temperatures above 300°C. Silicone rubber has excellent gas permeability, with an oxygen transmission rate that is among the highest in synthetic polymers. Additionally, silicone rubber is physiologically inert and does not cause blood clotting, making it widely used in medical applications.High-temperature performance. The most notable feature of silicone rubber is its high-temperature stability. Although its strength at room temperature is only half that of natural rubber or some synthetic rubbers, at temperatures above 200°C, silicone rubber can maintain a certain degree of flexibility, resilience, and surface hardness, with no significant changes in mechanical properties.Properties1. Low-temperature performance. The glass transition temperature of silicone rubber is generally between -70°C and -50°C, with special formulations reaching -100°C, indicating excellent low-temperature performance. This is highly significant for the aviation and aerospace industries.2. Weather resistance. The Si-O-Si bonds in silicone rubber are highly stable against oxygen, ozone, and ultraviolet light, providing excellent weather resistance without the need for additives.3. Electrical properties. Silicone rubber has outstanding insulation properties, with excellent corona and arc resistance.4. Physical and mechanical properties. At room temperature, the physical and mechanical properties of silicone rubber are inferior to those of general-purpose rubbers. However, at high temperatures of 150°C and low temperatures of -50°C, its physical and mechanical properties surpass those of general-purpose rubbers.5. Oil and chemical resistance. Ordinary silicone rubber has moderate resistance to oil and solvents.6. Gas permeability. At room temperature, the permeability of silicone rubber to gases such as air, nitrogen, oxygen, and carbon dioxide is 30-50 times higher than that of natural rubber. more>

Suitable for diesel engines, fuel systems, and sealing needs in chemical plants. Not recommended for use with ketones, low molecular weight esters, and nitrated mixtures. General operating temperature range: -20~250°C.Food grade silicone is an inorganic polymer colloid material formed by the condensation of silicic acid, with the main component being SiO2•nH2O, content above 98%. It is non-toxic, odorless, chemically stable, and does not react with any acids, alkalis, or salts under normal conditions except for caustic alkalis. It can withstand high temperatures up to 220°C, can be used in microwaves, and has no adverse effects on the human body. Compared to other materials, it is safer and healthier. Simply put, food-grade silicone has strong stability and better meets health and safety requirements. In fact, food-grade silicone is already found in ordinary households, commonly seen as sealing gaskets in pressure cookers, which are easy to clean and non-toxic.Applications of Food Grade Fluorine Rubber Sealing Rings:Fluoroelastomers are often used in the automotive industry, chemical processes, aerospace, and many industrial applications due to their excellent flame retardancy, air tightness, high-temperature resistance, oil resistance, solvent resistance, combustion resistance, chemical resistance, and weather resistance. Notably, fluoroelastomer seals can be used under high vacuum conditions, below 1.33*10^-7 Pa, where other rubbers cannot be used for sealing. Domestic and international manufacturers use this material to produce products; for example, Midea's product sealing rings are made from this type of material.Uses of fluorine rubber sealing rings: Automotive, locomotive, diesel engine, and fuel system sealing; sealing components in chemical plants.<img src="https://img-i-album.toocle.com/view/2022/04/06/b2/624d32f0597b2.jpg" style="max-width:100%;"/>I.
