Composed of synthetic rubber pad: synthetic rubber based on oil and natural gas as raw material, diene monomer and polymerization of olefin polymer. Polymer rubber has exceeded monomer process asbestos rubber gasket, the world's leading rubber factories have begun to use more strength silicone rubber gasket, made of ultra-high molecular aggregates, and fairly low cost. Hydrogenated NBR HNBR rubber: (Hydrogenate Nitrile) is carried out by the nitrile rubber obtained special hydrotreating a highly saturated elastomer. Hydrogenated nitrile rubber with good oil resistance (for fuel oil, lubricating oil, aromatic solvent resistant to good); and because of its highly saturated structure, making it a good heat resistance, excellent chemical resistance (for Freon, acids, alkalis has good resistance to) the rubber pad, excellent ozone resistance of rubber gaskets, high resistance to compression set properties; while hydrogenated nitrile rubber also has high strength, high tear strength, abrasion resistance Excellent features, overall performance is very good, one of the rubber. Advantages: better than the NBR has abrasion resistance, with excellent corrosion resistance, tensile, tear, and compression characteristics. Disadvantages: Not recommended for use in alcohols, esters, or aromatic solution into air conditioning and refrigeration industry, widely used in environmentally friendly refrigerant R134a system seals.
