Imports of seal wear and abrasion resistant EPDM rubber O-ring imported English name abbreviation EPDM EP. EPDM common color is black, also can be made into any color barrier, as long as you provide a sample color number or company Wal-top that you can produce it. EPDM rubber containing no double bond in the main chain is fully saturated straight-chain structure, a diene Jing its side chain, and can be vulcanized with sulfur. 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 does not resistant to aliphatic and aromatic solvents erosion. EPDM rubber has the lowest density is high filling properties, but lack of self-adhesive and mutual adhesiveness. In addition, EPDM has outstanding resistance to steam performance, such as the production of steam-resistant diaphragm seal products. EPDM has been widely used in washing machines, televisions and accessories doors and windows sealed products, or more complex profile strip production. Acid o-rings, o-rings and alkali resistance in the trench initial deformation (interference) its sealing capability is very important: 1. Obtain initial sealing contact ability 2. Compensation product tolerance (in the gaps, connection between the two) 3. 4. compensation guarantee a certain friction-ring compression set 5.O compensate for wear than providing information on 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 materials o-ring .
