EPDM Rubber (Ethylene Propylene Rubber) Excellent Performance and Diverse Applications
EPDM (Ethylene Propylene Rubber) is a terpolymer of ethylene and propylene. After sulfur or peroxide cross-linking treatment, it exhibits excellent weather resistance, ozone resistance and UV resistance, and can maintain excellent elasticity even at extremely low temperatures. This material is widely used in a variety of industries and has good chemical resistance (to dilute acids, alkalis and polar solvents), and has excellent electrical insulation properties, meeting multiple international safety standards.
Curing and Strengthening Treatment Sulfur-bridged EPDM has high elasticity and is suitable for general industrial needs, while the peroxide-bridged version provides better heat resistance and compression set performance, suitable for high temperature and long-term use applications, such as hoses in the construction industry and high-end industrial seals.
Food and Drinking Water Safety Standards In terms of application areas, EPDM rubber can be formulated according to FDA 21.CFR 177.2600 standards to meet the safety needs of the food and beverage industry. In addition, it can also be certified by NSF (National Sanitation Foundation) to ensure safety and reliability in drinking water systems.
Automotive and Industrial Applications EPDM rubber is widely used in air conditioning systems in the automotive industry. It is suitable for the use of modern environmentally friendly refrigerants (such as R744) and maintains excellent resistance to CO2 explosive decompression under high pressure and high temperature environments. In addition, it is also suitable for systems containing phosphate ester hydraulic oils, showing excellent stability and durability. EPDM's diverse applications include vehicle seals, outdoor seals, hoses, and high temperature and high pressure industrial fields. It is the material of choice for many industries around the world.
