Brief Introduction to Food Grade Fluorine Rubber Sealing Rings:

Food grade silicone sealing rings are made from food-grade silicone raw materials, primarily emphasizing environmental performance. The products pass environmental SGS test reports such as UL, ROSH, RECH, 6P, FDA, NSF, etc. Product specifications include food-grade silicone sealing rings, food-grade silicone U-shaped sealing rings, food-grade silicone Y-shaped sealing rings, food-grade silicone V-shaped sealing rings, food-grade气相 silicone sealing rings, food-grade rectangular silicone sealing rings, food-grade conductive silicone sealing rings, etc.
Food grade fluorine rubber sealing rings—superior high-temperature resistance compared to silicone rubber, excellent weather resistance, ozone resistance, and chemical resistance, but poor cold resistance. Resistant to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. 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.
