1, natural rubber (NR) Natural rubber hydrocarbon rubber (polyisoprene) based, with a small amount of protein, water, resin acids, sugars and inorganic salts. Natural rubber elasticity, elongation, high strength, tear resistance and excellent electrical insulation, wear resistance and good drought tolerance, processing, good, natural rubber adhesive and easy with other materials, in terms of overall performance is better than most synthetic Rubber. The disadvantage of natural rubber is resistant to oxygen and poor ozone resistance, easy to aging deterioration; bad oil and solvent resistance, low resistance to low pH in corrosion; heat resistance is not high. Natural rubber Temperature range: about -60 ¡æ ~ +80 ¡æ. For the production of natural rubber tires, rubber shoes, hose, tape, wire and cable insulation and sheathing, and other common products. Especially for the manufacture of natural rubber torsional vibration elimination, engine damper, the machine bearings, rubber - metal suspension components, diaphragm, molded products.

 2, styrene butadiene rubber (SBR) and styrene butadiene styrene butadiene rubber is a copolymer. SBR performance close to natural rubber, is the most common current production of synthetic rubber, styrene butadiene rubber is characterized by resistance, aging resistance and heat resistance than natural rubber, natural rubber also more uniform texture. SBR's weaknesses are: low elasticity, flex resistance, tear resistance is poor; processing performance is poor, especially poor self-adhesive, gum low strength. SBR operating temperature range: about -50 ¡æ ~ +100 ¡æ. Mainly to styrene-butadiene rubber tires instead of natural rubber production, rubber, rubber hose, rubber shoes and other common products.

 3, butadiene rubber (BR) butadiene rubber made ​​by polymerization of butadiene rubber, cis-structure. Butadiene rubber advantages: flexibility and good abrasion resistance, aging resistance, good low temperature resistance and excellent dynamic heat load is small, easy-to-metal bonding. BR drawback is the low intensity and poor tear resistance, processing performance and poor self-adhesive. Butadiene rubber Temperature range: about -60 ¡æ ~ +100 ¡æ. More commonly and natural rubber or styrene butadiene rubber and use, the main production of butadiene rubber tread tires, conveyor belts and special cold-resistant products.
