Is The Structure Of Rubber?

Branched structure: The aggregation of the branches of the rubber macromolecule chain, and the rubber fenders form a gel. Gels are detrimental to rubber performance and processing. When mixing, various compounding agents often cannot enter the gel area, forming a local blank, and the rubber fenders cannot form reinforcement and cross-linking, becoming a weak part of the product.

Cross-linked structure: Linear molecules are connected to each other through the bridging of some atoms or groups of atoms, and the rubber fenders form a three-dimensional network structure. Shows that with the progress of the vulcanization process, this structure is continuously strengthened. Like rubber fenders, the free movement ability of the chain segments is reduced, the plasticity and elongation are reduced, the strength, the elasticity and hardness of the rubber fenders are increased, the compression set and the swelling degree decline.

Excerpt: Aggregation of the branches of the rubber macromolecule chain to form a gel. Rubber fender gel is detrimental to the performance and processing of insulating rubber sheets. During compounding, various compounding agents often cannot enter the gel area, forming a local blank, and the rubber fenders cannot form reinforcement and cross-linking, becoming a weak part of the product.

Linear structure: the general structure of unvulcanized rubber. Due to the large molecular weight, the macromolecular chain has a random curvilinear cluster shape without external force from the rubber fender. When an external force is applied and the external force is removed, the entanglement of the rubber fender thread group changes, the molecular chain rebounds, and a strong tendency to recover is produced. This is the origin of high elasticity of rubber.
