Rubber
Rubber is an important material used in automobiles. Rubber parts on a car account for about 6%~10% of the total vehicle quality. For example, tires, hoses, seals, anti-vibration parts, transmission parts, village cushions and so on, their main characteristics are high elasticity: under the action of a small external, they can produce great elastic deformation (elongation, compression, bending, etc.). After removing the external force, it can return to its original state in a very short time; vibration absorption capacity: rubber can absorb a part of mechanical energy and convert it into thermal energy. Rubber has certain corrosion resistance, wear resistance and insulation.
Rubber is a kind of macromolecule material which is based on raw rubber and is composed of some admixtures (vulcanizate, activator, softener, filler, antioxidant, etc.). According to the source of raw rubber, it can be divided into natural rubber and synthetic rubber.
