What is the rubber industry?

Because in the field of chemistry, rubber is a polymer compound, an aromatic hydrocarbon, and has a special fragrance.

It is elastic at room temperature, can produce large deformation under the action of a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (T g) and a molecular weight that is often large, greater than hundreds of thousands.

Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in various aspects of industry or life.

Development situation:

The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. It can be seen that the rubber industry has a wide range of products and the backward industries are very broad.

In recent years, the rubber industry has achieved a lot of development. The existing sub-industries have been growing steadily, and the new rubber sub-industries are developing rapidly. However, at the same time, the rubber industry also has environmental, resource, and disaster problems. , innovation and other issues.

In 2004, the total natural rubber planting area nationwide was 696,200 hectares, the harvested area was 451,900 hectares, and the dry rubber output was 573,300 tons. Among them, the agricultural reclamation rubber planting area is 411,000 hectares and the private rubber planting area is 285,200 hectares, accounting for 59.03% and 40.97% of the country's total rubber area respectively.
