Question:

Colorful cars are mainly made of plastic, rubber and other materials?

Colorful cars are mainly made of plastic, rubber and other materials?

Answer:

The most essential difference lies in the plastics and rubber plastic deformation occurs in plastic deformation, while the rubber is elastic deformation. In other words, not easy to restore the original state of plastic deformation, and the rubber is relatively much easier. The elastic plastic is very small, usually less than 100%, while the rubber can reach 1000% or more plastic. In the vast majority of molding forming process of finished products is finished; and the rubber molding process after the curing process is needed.
Rubber can be divided into natural rubber and synthetic rubber in two categories:Natural rubber: cutting by rubber tree, mucilage collected out, after removing impurities, solidification, smoke, drying process, raw material and the formation of.2. synthetic rubber by-products produced by the petrochemical industry, according to the different needs of different raw material was synthesized. The properties such as: SBR, NBR, EPDM, BR, IIR, CR, Q, FKM and so on. But because of the difference in synthetic way, similar material can be divided into several different types of rubber. Through the setting of any type of rubber, rubber material can be changed into hundreds of products with demand.Natural rubber from rubber trees in tropical and subtropical regions. Because the rubber has an important role in industry, agriculture, national defense field, so it is an important strategic material, which prompted the lack of rubber resources of the country in the research and development of synthetic rubber.
Plastic and rubber are high molecular material, mainly composed of two kinds of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, fluorine, silicon, sulfur atoms, its special properties, use is also special. At room temperature, the plastic is not solid, hard, and tensile deformation of rubber hardness is not high., elastic, can be stretched, and stop pulling back to normal. This is due to differences in their molecular structure. Another difference is the plastic can be repeatedly recycled, while the rubber cannot be directly recycled, can only be processed and then reclaimed rubber, plastic and rubber. Available in the form of more than 100 to 200 degrees at 60 to 100 degrees. The morphological similarity does not include plastic rubber.
