Now there are many kinds of rubber plates, according to different classification methods, there are different categories. At present, the main use of source and use classification methods.
Rubber Plate Classification According to the source use classification, mainly divided into two major categories: one is natural rubber plate NR, and two is synthetic rubber board. Natural rubber is obtained from the plant, processing procedures are mainly tapping, dilution, filtration, solidification, drying made. Natural rubber plate is mainly made of natural rubber plus a mixture, filler and vulcanization. Natural rubber Plate The most critical performance has good elasticity, tensile strength, tearing resistance, high insulation, strong adhesion, easy to process and so on. Synthetic rubber is a synthetic high elasticity polymer, a lot of species, each has characteristics, widely used.
Synthetic rubber board is divided into two categories: one is general rubber plate, and the other is special rubber plate. General Rubber Board a wide range of main types of SBR, styrene Butadiene Rubber plate BR, NITRILE rubber plate NBR, neoprene board CR, Butyl Rubber Board IIR, EPDM, ethylene propylene diene and so on. Styrene-Butadiene rubber products mainly have good resistance to wet sliding, low rolling resistance and good wear resistance, according to its performance as long as it does not require oil-resistant, heat-resistant, no special requirements of the occasion can be used. The performance of BR is close to that of styrene butadiene rubber. EPDM has excellent resistance to ozone aging, heat resistance, weather aging, water resistance, chemical media, excellent electrical insulation performance. The properties of butyl rubber are similar to EPDM rubber, but they are less than ethylene-propylene rubber, with the best tightness and damping; Nitrile rubber is good for oil resistance, heat-resistant and antistatic. Neoprene has a relatively good heat-resistant, ozone resistance, weathering aging, with flame retardant, good adhesion characteristics.
Special Rubber Board performance, with the general Rubber Board does not have special performance, but the price is expensive. The most commonly used mainly have silica gel plate and fluorine rubber plate. Silica gel plate is characterized by high temperature, low temperature resistance, the best ozone resistance, corona resistance, breathable. Fluorine rubber plate has the characteristics of high temperature resistance, oil resistance, corrosion resistance, vacuum resistance, and the best effect of flame retardancy.
