Imported EPDM O-rings EPDM EPDM EPDM conjugated ethylene, propylene and a non-diene polymerization. EPDM EPDM main polymer chain is completely saturated, this feature makes the EPDM EPDM O-rings can resist heat, light, oxygen, etc., especially ozone. 2 / EPDM rubber O-ring feature, EPDMO-ring, EPDM O-ring: 1) EPDM EPDM O-ring has a remarkable resistance to oxidation, ozone and anti-erosion; 2) EPDM EPDM O-rings with excellent aging ability, was praised as no cracks rubber; 3) EPDM O-rings with good flexibility and resistance to compression deformation; 4) EPDMO seals Circle has a low density and high filling; 5) because it is EPDM EPDM O-rings essentially nonpolar, so EPDM EPDM O-rings on the polar solvents and chemicals with strong resistance and good insulation properties, but poor water density. In terms of resistance to chemical acid corrosion generally fluorine rubber or EPDM O-ring, simply the difference: fluorine rubber resistant to chemical energy broader, higher temperature resistant fluorine rubber, can 240 degrees, and EPDM O-rings can only reach 150 degrees, fluorine rubber oil tired medium can, and EPDM not. EPDM rubber has the advantage of lower prices, more for sewage or other water treatment products. EPDM EPDM rubber English name abbreviation EP. EPDM common color is black, also can be made into any color barrier, as long as you provide Color sample Wall top company or think that you can produce it. EPDM backbone is no double fully saturated straight chain structure, a diene Jing on its side chain, so you can use sulfur vulcanization. EPDM has excellent resistance to aging, ozone resistance, weather resistance, heat resistance (120 ℃ environment in long-term use), chemical resistance (such as alcohols, acids, alkalis, oxidizing agents), but not resistant to aliphatic and aromatic solvents erosion. EPDM rubber is the lowest density high filling properties, but the lack of mutual self-adhesive and sticky. In addition, EPDM has outstanding steam resistance, can be made resistant to steam diaphragms seal products. EPDM rubber is widely used in washing machines, television sets and accessories doors and windows sealed products, or more complex profile strip production. Acid o-rings, alkali resistance o-ring in the groove of the initial deformation (interference) its sealing capability is very important: 1. 2. Ability to obtain an initial sealing contact with tolerance compensation products (in bond gaps connect both) 3. 4. compensation guarantee a certain friction-ring compression set 5.O compensate for wear
