For the application of common synthetic rubber, not too long or too difficult, want to do
Styrene butadiene rubber (SBR) copolymer of butadiene and styrene. The performance is close to natural rubber, is currently the largest production general synthetic rubber, which is characterized by abrasion resistance, aging resistance and heat resistance than natural rubber, natural rubber texture is uniform. The shortcoming is: low elasticity, flex, poor anti tearing properties; processing poor performance, especially since the viscosity difference, green strength is low. The temperature range of about 50 DEG C: ~100. Mainly used to replace natural rubber tire, rubber hose, rubber plate, making shoes and other generic products.
Isoprene rubber (IR) is a kind of structure of rubber from the CIS isoprene monomer polymerization. The chemical composition, and three-dimensional structure of natural rubber is similar to that of the performance is very close to the natural rubber, synthetic natural rubber said. It has most of the advantages of natural rubber, aging due to natural rubber elasticity and strength. Slightly lower than natural rubber, poor processing performance, high cost. Use temperature range: - 50 DEG C ~ + 100 DEG C can be used instead of natural rubber tires, rubber shoes, rubber hose, making tape and other generic products.
Natural rubber (NR) with rubber hydrocarbon (polyisoprene), containing a small amount of protein, carbohydrate, moisture, acid resin and inorganic salts. Flexibility, high tensile strength, tear resistance and excellent electrical insulation, good wear resistance and drought tolerance, processing of good, easy to other materials than in adhesive the performance of most synthetic rubber. The disadvantage is resistance to oxygen and ozone resistance, easy aging deterioration; oil resistance and solvent resistance is not good, the anti acid corrosion resistance low; heat resistance is not high. The temperature range of about - 60 DEG C ~ + 80 DEG C. Production of tires, rubber shoes, rubber hose, rubber belt wire and cable insulation and sheath as well as other common products. Especially suitable for manufacturing the torsional vibration eliminator, engine shock absorber, machine bearings, rubber metal diaphragm, suspension components, molded products.
Polybutadiene rubber (BR) is formed by polymerization of butadiene rubber CIS structure. The advantages are: flexibility and excellent abrasion resistance, good aging resistance, low temperature resistance is excellent in heat under dynamic load is small, easy to metal bonding. The disadvantage is low strength, tear resistance, processability and self-adhesive poor. Using temperature range: - 60 DEG C ~ + 100 DEG C. The general and natural rubber or butadiene rubber and tire tread, main production and transportation with cold and special products.
Chloroprene rubber (CR) by chloroprene do monomer emulsion polymerization and into the polymer. This rubber molecule containing chlorine atom, so compared with other general rubber: it has excellent oxidation resistance, ozone resistance, non flammable, after the fire can be self extinguishing, the advantages of oil resistance, solvent resistance, acid and alkali aging resistance, good air tightness; the mechanical performance is better than natural rubber, it can be used for general rubber, also can be used for special rubber. The main disadvantage is poor cold resistance, large proportion, relatively high cost, good electrical insulation, processing is easy to stick rolling, easy to scorch and easy sticking. In addition, rubber poor stability, not easy to save. The temperature range of about - 45 DEG C ~ + 100 DEG C. Mainly used in the manufacture of anti ozone aging resistance, high cable sheath and various protective cover, protective cover; oil resistance, chemical corrosion resistance of hose, adhesive tape and chemical lining Flame resistant underground mining rubber products, as well as a variety of molded products, seals, mats, adhesives and so on
