Rubber Pads Divide it into
Classification and Analysis of Rubber Cushions
The main products of the rubber pad can be divided into four categories: nitrile rubber mat, silicone pad, fluorine rubber pad, other rubber pad.
Fluorine rubber pad: has a good high temperature performance, can be -20 ℃ - +200 ℃ environment which was used, not only that, it also has a strong antioxidant, oil and acid. Will generally be used in high temperature, high vacuum, high pressure environment, of course, is also more suitable for use in the oil environment. Therefore, widely used in the oil, chemical, aviation, aerospace and other corresponding departments.
Nitrile rubber mat: Butadiene, acrylonitrile by emulsion copolymerization of the polymer, with its excellent oil resistance named, at the same time also has a very prominent wear resistance, aging resistance, air tightness. So its use in the rubber industry is also relatively wide.
Silicone pads: High and low temperature resistance compared to the prominent, under normal conditions in the -70 ℃ - + 260 ℃ temperature range can maintain its superior use of elasticity. At the same time, because of its own good resistance to ozone, weather resistance of the advantages of aging, so more suitable for thermal machinery in the sealing gasket. Silicone rubber has a high resistance to high and low temperature performance, in the -70 ℃ - +260 ℃ temperature range to maintain good use of elasticity, ozone resistance, weather resistance, should be used in the thermomechanical seal gasket. Non-toxic can produce insulation, insulation products and medical rubber products. It is widely used in machinery, electronics, plumbing and other industries, our production of silicone pads in line with EU environmental standards and the EU food-grade standards.
Nitrile rubber is composed of butadiene and acrylonitrile emulsion copolymerization of the polymer, with its excellent oil resistance is known, but also has good wear resistance, aging resistance and air tightness, and thus in the rubber industry Widely used.
Fluorine rubber gasket with high temperature resistance, can be -20 ℃ - +200 ℃ environment, strong antioxidant, oil, acid and alkali. Usually used in high temperature, high vacuum and high pressure environment, but also suitable for oil environment. With a variety of excellent performance, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other departments.
Other neoprene, natural rubber, EPDM rubber, acrylic adhesive and other special rubber. With oil, acid, alkali, wear resistance, high resistance, low temperature and other characteristics.
