The structure of rubber and plastic material constitutes the general structure of linear structure of unvulcanized rubber and plastic. Because of its large molecular weight, it is in the shape of a fine cluster without external force. When the external force is applied and removed, the entanglement degree of the fine group changes, and the molecular chain rebounds, resulting in a strong recovery tendency, which is the origin of high elasticity of rubber and plastic. Branched chain structure: the aggregation of branched chains of macromolecular chains of rubber and plastics, forming gels. Gels are not good for the performance and processing of rubber and plastics. In the process of making rubber, all kinds of complexing agents often improve the gel area and form partial blank, which can not form reinforcing and cross-linking, and become the weak part of the product.
