Plastic and rubber distinguish between plastic and rubber

Plastic and rubber is the most essential difference between plastic deformation occurs when the plastic deformation, and rubber is elastic deformation. In other words, the plastic deformation is not easy to restore the original state, and the rubber is relatively much easier. The elasticity of plastics is very small, usually less than 100%, while the rubber can reach 1000% or more. Plastics in the forming process of the vast majority of the molding process is completed, and the rubber forming process after the need to be vulcanized process.
