Imported EPDM rubber O-rings in terms of chemical acid corrosion generally fluorine rubber or EPDM O-ring, simply the difference: fluorine rubber resistant to chemical energy broader, fluorine rubber resistant to temperature will be higher, up to 240 degrees, and EPDM O-rings can only reach 150 degrees, fluorine rubber can be oil tired media, 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 providing information on more than compensate for wear EPDM EPDM o-rings from Taiwan Wall OTP top physical characteristics, its main acid characteristics, in addition to NBR nitrile rubber o-rings, VITON fluorine rubber o-rings, SIL silicone silicone rubber o-rings, AEM butyl rubber o-rings, etc. Other material o-ring .
