Rubber, with plastic, fibers, are called three major synthetic materials, and is the only polymer material having high scalability and excellent elasticity. The big feature of rubber is first, the elastic modulus is very small, and the elongation is high.
Second, it has a relatively good gas genetic and resistance to various chemical media and electrical insulation. Certain special synthetic rubber has a better oil resistance and temperature resistance, resisting fatty oil, lubricating oil, hydraulic oil, fuel oil, and solvent oil; cold resistance can be low to -60 ° C to -80 ° C, heat resistance High to + 180 ° C to + 350 ° C. Rubber also resists a variety of flakes, bending deformation, because the lag loss is small.
The third feature of the rubber is that it can be used, blended, composite, which is modified to obtain good comprehensive performance with a variety of materials.
