quality EPDM oxygen O-ring in china is polymerized from ethylene, propylene and non-conjugated dienes. The main polymer chain of EPDM EPDM is fully saturated, this feature makes quality EPDM oxygen O-ring in china resistant to heat, light, oxygen, etc., especially ozone.

The characteristics of quality EPDM oxygen O-ring in china: 1) EPDMO ring has extraordinary resistance to oxidation, ozone and erosion; 2) EPDMO ring has excellent anti-aging ability, and is praised as a crack-free rubber; 3) EPDM O-ring has good elasticity and resistance to compression deformation; 4) EPDMO type sealing ring has low density and high filling; 5) Due to the quality EPDM oxygen O-ring in china is non-polar in nature Therefore, EPDM EPDM O-rings have strong resistance to polar solutions and chemicals and good insulation properties, but poor water tightness.
In terms of chemical acid and alkali corrosion resistance, fluorine rubber or quality EPDM oxygen O-ring in China is generally used. Simply put, the difference between the two is: fluorine rubber has wider chemical resistance, and fluorine rubber has higher temperature resistance, which can reach 240 degrees, while the EPDM O-ring can only reach 150 degrees, fluorine rubber can resist oily media, but EPDM rubber cannot. The advantage of EPDM rubber is that its price is low, and it is mostly used in sewage treatment or other water treatment products.
