NBR NBR rubber pad: (Nitrile Rubber) from acrylonitrile butadiene polymerization with rubber gaskets, acrylonitrile content from 18% to 50%, higher acrylonitrile content of petrochemical oil hydrocarbon fuel resistance, the better, but the low temperature performance is poor, the general temperature range of -25 ~ 100 ℃. NBR is one of the most commonly used rubber seals and O-rings present. Advantages: a good resistance to oil rubber plant, resistant to water, solvents and anti-high-voltage characteristics of the oil, with good compression resistance asbestos rubber gasket, anti-wear and elongation force. Disadvantages: not suitable for use in polar solvents being, for example, ketones, ozone, nitro hydrocarbons, MEK and chloroform for the production of the fuel tank, hydraulic oil tank and the oil in petroleum, gasoline, water, silicone oils, diesters.? Department of lubricants and other fluid medium used rubber parts, especially the sealing parts. It can be said is the most versatile, low cost rubber seals. 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), excellent ozone resistance, high resistance to compression set properties; while hydrogenated nitrile rubber also has high strength, high tear strength, excellent wear resistance and other characteristics, is one of the very good performance of rubber synthesis. 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.
