1.Natural rubber (NR) is mainly composed of rubber hydrocarbon (polyisoprene), containing a small amount of protein, water and tree fatty acids, sugars, inorganic salts, etc. Large elasticity, high tensile strength, excellent tear resistance and electrical insulation, wear resistanceIt is easy to bond with other materials and superior to most synthetic materials in comprehensive properties rubber. The disadvantages are poor oxygen and ozone resistance, easy to aging; poor oil and solvent resistance, the first acid resistance alkali has low corrosion ability and low heat resistance. Operating temperature range: about 60 ° C to + 80C. Making tires rubber shoes, rubber hose, tape, insulating layer and sheath of wires and cables and other general products. Especially suitable for system torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension element, diaphragm, mould pressing product.
2.Styrene butadiene (SBR) copolymers of butadiene and styrene. Its properties are close to that of natural rubber, and it is the general synthetic rubber with the largest output at present. It is characterized by wear resistance, aging resistance and heat resistance, and its texture is more uniform than that of natural rubber. The disadvantages are: low elasticity, poor flexibility and tear resistance; poor processing performance, especially poor self-adhesive and raw rubber strength. Operating temperature range: about – 50c ~ + 100C. It is mainly used to replace natural rubber to make tires, rubber plates, rubber tubes, rubber shoes and other general products.
Butadiene rubber (BR) is a kind of CIS structural rubber which is polymerized from butadiene.
It has excellent wear resistance, aging resistance, low temperature resistance, small heat output under dynamic load, and is easy to bond metal. The disadvantages are low strength, poor tear resistance, poor processability and self adhesion. Operating temperature range: about – 60 ° C to + 100C. -It is mainly used to make tire tread, transportation belt and special cold resistant products.
Cable lining adhesive has many applications in in all aspects.
