          Rubber gasket material of rubber classification

          Hits:Updated:2016-10-08 08:10:13【Print】

            Rubber gaskets are widely used in automotive, lighting and various machinery and equipment industries, mainly play tight seal, shock buffer, anti-static, electrical insulation, electronics, chemicals, antistatic, flame retardant, food, machinery and equipment industries , Can play a cushion, sealing, cushioning and so on. The main rubber material: NBR, SBR, CR, EPDM ... Rubber gasket with oil, acid, cold heat, anti-aging properties, can be directly cut into various shapes of gaskets, widely used in medicine, electronics , Chemical, anti-static, fire-retardant, food and other industries. It is widely used in medicine, electronics, chemical industry, antistatic, flame retardant, foodstuff and other industries. It can be directly cut into various shapes of gaskets. It has the characteristics of oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance and so on. Rubber gasket rubber gasket in the metal flange or other connection between the two stationary surface sealing effect of sheet rubber products collectively referred to as rubber gaskets. Silicone rubber gasket referred to as WMQ, silicone rubber has outstanding resistance to high and low temperature performance, -70 ℃ - +260 ℃ temperature range to maintain good flexibility, and ozone resistance, weather aging, etc., should be for the heat Sealing gaskets in machinery. Rubber gaskets are widely used in automotive, electronics, chemical, antistatic, flame retardant, food, machinery and equipment industries, can play a cushion, sealing, cushioning and so on.
            Silicone Rubber
            Has outstanding resistance to high and low temperature performance, -70 ℃ - +260 ℃ temperature range to maintain good use of elasticity, ozone resistance, weather aging, thermal machinery should be in the sealing gasket. Non-toxic insulation can be made, insulation products and medical rubber products. Our products are widely used in machinery, electronics, plumbing and other industries. Our silicone pads meet the EU environmental standards and EU food-grade standards. Our products are widely used in water treatment, water treatment,
            Nitrile rubber
            NBR (Nitrile-Butadiene Rubber) is a copolymer of butadiene and acrylonitrile by emulsion copolymer, known for its excellent oil resistance, but also has good wear resistance, aging resistance and air tightness , And therefore widely used in the rubber industry.
            fluororubber
            With high temperature resistance, can be -20 ℃ - +200 ℃ environment, strong oxidants, oil, acid and alkali resistance. Usually used in high temperature, high vacuum and high pressure environment, but also suitable for oil environment, widely used in petroleum, chemical, aviation, aerospace and other departments.

            NBR, SBR, CR, EPDM ... rubber gasket with oil, acid, cold heat, anti-aging properties, can be directly cut into various shapes of gaskets, widely used in medicine, electronics, chemicals, Static, fire-retardant, food and other industries.
            Silicone rubber gasket (WMQ)
            With outstanding resistance to high and low temperature performance, in the -70 ℃ - +260 ℃ temperature range to maintain a good use of bombs ...
            Nitrile rubber gasket (NBR): is a copolymer of butadiene and acrylonitrile copolymerization by the polymer. Nitrile rubber gasket with its excellent oil resistance (but not ketone, ester and chlorinated hydrocarbons and other media) is known, but also has good wear resistance, aging resistance and air tightness, which in the rubber industry In a wide range of applications.
            Fluorine rubber gasket
            With high temperature resistance, can be -20 ℃ - +200 ℃ environment, strong oxidants, oil, acid and alkali resistance. Usually used for high temperature, high vacuum and high pressure environment, but also suitable for oil environment. As a result of a variety of excellent performance, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other departments.
            Other rubber gaskets
            Neoprene, natural rubber, EPDM rubber, acrylic rubber and other special rubber.
            The main parameters / rubber gasket editing
