Branched chain structure: aggregation of branched chains of rubber macromolecules to form a gel.

Gels are detrimental to the properties and processing of rubber.

In the process of rubber refining, a variety of additives often can not enter the gel area, forming a local blank, can not form reinforcement and cross-linking, become the weak part of the product.

Crosslinked structure: linear molecules are connected to each other by a bridge of atoms or groups, forming a three-dimensional network.

Rubber fender plant said, as the vulcanization process, the structure of the strengthening.

Thus, the free activity of the chain segment decreases, plasticity and elongation decrease, strength, elasticity and hardness increase, and compression permanent deformation and swelling decrease.

Selection: aggregation of branched chains of rubber macromolecules to form a gel.

Gel is not good for the properties and processing of insulating rubber sheet.

In the process of rubber refining, a variety of additives often can not enter the gel area, forming a local blank, can not form reinforcement and cross-linking, become the weak part of the product.

Linear construction: general construction of unvulcanized rubber.

Due to its large molecular weight, the macromolecular chain is shaped like a random roll curve with no external force.

When the external force action, remove the external force, the entanglement of the thread group changes, molecular chain rebound, a strong recovery tendency, this is the origin of rubber high elasticity.
