Rubber is a necessary material for the manufacture of aircraft, warships, automobiles, tractors, harvesters, irrigation and irrigation machinery, medical equipment and so on. Depending on the source,
Rubber can be divided into natural rubber and synthetic rubber. Natural rubber is wear-resistant, easy to process, less environmental pollution, but the output is limited, and it is suitable for use
The temperature requirement is relatively high.
Synthetic rubber is a polymer based on oil and natural gas as raw materials, polymerized by diolefin and olefin as monomers, and began production in the early 20th century
It has developed rapidly since 1990. Synthetic rubber is generally not as comprehensive as natural rubber in performance, but it has high elasticity, insulation, air tightness,
Oil resistance, high or low temperature resistance and other properties, so widely used in industry and agriculture, national defense, transportation and daily life.
