The rubber is a high-elasticity polymer material with reversible deformation, is rich in elasticity at room temperature, can generate large deformation under the action of small external force, and can recover the original shape after the external force is removed. The rubber belongs to a completely amorphous polymer, and has low glass transition temperature and large molecular weight which is more than hundreds of thousands. The rubber is divided into natural rubber and synthetic rubber. The natural rubber is prepared by extracting colloid from plants such as rubber tree and rubber grass and processing; synthetic rubbers are obtained by polymerization of various monomers. Rubber products are widely used in industry or in various aspects of life.
The primary operation of an automotive cooling system is to dissipate heat into the air to prevent overheating of the engine, but the cooling system has other important roles. The engine in the automobile is best operated under a proper high-temperature state.
