Company Introduction:
Suzhou Yongxin Technology is a supplier of sealing components in motion and control systems, providing sealing solutions for transmission control, automation equipment, and aviation, selling various seals, hydraulic, pneumatic, and fluid control products and components. In terms of seals, Yongxin offers hydraulic seals and pneumatic seals, including dynamic seals, static seals, sealing rings, oil seals, gaskets, packing, etc.

Product Introduction:
Ethylene propylene rubber is copolymerized from ethylene and propylene, with no double bonds in the main chain, thus offering excellent heat resistance, weather resistance, and ozone resistance. At an ozone concentration of 100x10(pphm), it does not develop cracks for 2430 hours, with an outdoor lifespan of over 25 years. In 160℃ steam, EPDM also performs better than other general-purpose rubbers. It also has good resilience, insulation properties (volume resistivity about 10^16 Ω·cm, breakdown voltage 30-40 kV/mm), and low-temperature resistance (Tg = -60℃). EPDM (Ethylene Propylene Diene Monomer) is suitable for glycol-based brake fluids below 150℃, hot water and steam (up to 150℃), silicone oil and grease, animal and vegetable oils, most organic or inorganic acids, detergents, alkaline or high-potassium environments, most polar solvents (ketones, alcohols, esters), phosphate ester hydraulic oils, and refrigerant R134a+PAG systems. It performs well in oxygen-depleted water and ammonia environments and can also be used in acetic acid environments below 3%-5%, but is not suitable for mineral oils, greases, and aromatic or hydrocarbon solvents. The disadvantages of EPDM are slow vulcanization speed, inability to co-vulcanize with diene rubbers, poor self-adhesion and mutual adhesion, and poor air tightness.
Temperature range: -55℃ to 125℃, up to 150℃ with peroxide vulcanization.
Hardness range: Shore A 40 to 90.
Main color: black, but can be customized as per customer requirements.

Product Features:
1. High cost-effectiveness, raw rubber density only 0.86～0.90 kg/m³, making it the lightest commonly used rubber; and it can be heavily filled to reduce material costs.
2. Excellent aging resistance, including weather, ozone, sunlight, heat, water, steam, UV, and radiation resistance. When blended with other unsaturated diene rubbers such as NR, SBR, BR, NBR, and CR, EPDM acts as a polymeric antioxidant or anti-aging agent.
3. Excellent chemical resistance to acids, alkalis, detergents, animal and vegetable oils, alcohols, etc.; outstanding resistance to water, hot water, and steam; and resistance to polar oils.
4. Superior insulation properties, with volume resistivity of 10^16 Ω·cm, breakdown voltage of 30～40 MV/m, and dielectric constant (1kHz, 20℃) of 2.27.
5. Wide applicable temperature range, with a low operating temperature of -40～-60℃ and long-term use at 130℃.
Application Range:
EPDM is widely used in the automotive industry for making partitions, hoses, dust covers, brake components, radiator and engine connection hoses, shock absorbers, and door and trunk seals. In the construction industry, EPDM is used with asphalt as waterproofing material, shock absorption products in bridge engineering, and sealing strips for high-rise steel doors. It is also used for indoor rubber flooring. EPDM can serve as insulation material for transformers and other high, medium, and low-voltage insulation products, as well as components in household appliances such as refrigerator seals, parts for heaters and air conditioners, washing machine seals, vacuum cleaner parts, and inflatable rubber boats.
Mainly used in automotive seals, radiator hoses, spark plug boots, air conditioning hoses, gaskets, and hoses. In the automotive seal industry, EPDM is valued for its elasticity, ozone resistance, and weather resistance. Due to its excellent water resistance, heat and cold resistance, and weather resistance, as well as ease of installation, EPDM is widely used in the construction industry for plastic sports fields, waterproof membranes, door and window seals, glass curtain wall seals, sanitary equipment, and pipe seals.
