Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under the action of a small external force. After removing the external force, it can return to its original state.Rubber is a completely amorphous polymer, its glass transition temperature (T g) is low, molecular weight is often large, more than several hundred thousand.
PVC is plastic.It is a vinyl chloride monomer (VCM) initiator of peroxide, azo, etc.Or under the light, heat action according to the radical polymerization reaction mechanism polymerization polymer.Vinyl chloride homopolymers and copolymers are called vinyl chloride resins.
The most essential difference between rubber and plastic is that plastic deformation occurs when plastic deformation, and rubber is elastic deformation.Plastic does not easily revert to its original state after deformation, while rubber is much easier.The plastic is basically finished, but the rubber still needs to be vulcanized.Rubber is commonly used in electronics, medical, chemical, aerospace and other fields, plastics are mainly used in construction, industry, defense cutting-edge industry and People's Daily life and other fields.
