Overview of rubber sole materials in Dongguan

The concept of rubber shoe material in Dongguan rubber sole factory
1. Rubber shoe material: The definition of rubber shoe material commonly used in the world is quoted from the American national standard ASTM-D1566 (America Society of Test and Material). The definition is as follows:
Rubber shoe material is a kind of material, which can quickly and powerfully restore its deformation under large deformation, and can be modified (vulcanized). The modified rubber shoe material is substantially insoluble in boiling benzene and methyl ethyl ketone except for swelling. , ethanol-toluene mixture and other solvents. The modified rubber shoe material is stretched to twice the original length at room temperature (1829 degrees Celsius) and persisted for one minute. After the external force is removed, it can recover to 1.5 times the original length within one minute. The material with the above characteristics is called rubber shoe material. The sole made by Dongguan Rubber Sole Factory is made of this kind of material.
Note:
①Rubber shoe material is a kind of material, which has specific use function and processing function, and belongs to organic polymer material.
②Rubber shoe material has high elasticity at room temperature.
③The rubber shoe material can be modified, which means it can be vulcanized.
④Modified rubber shoe material, that is, vulcanized rubber, does not dissolve but can swell.

2, raw rubber:
There are rubber shoe materials that have joined the compounding agent and have not been cross-linked. It is usually composed of linear macromolecules or linear macromolecules with branched chains, and can be dissolved in organic solvents.

3, Mixed rubber:
Raw rubber and compounding agents are processed and mixed evenly and have not been cross-linked. Commonly used compounding agents include vulcanizing agents, accelerators, active agents, reinforcing fillers, anti-aging agents, etc.

4, vulcanized rubber:
The rubber shoe material obtained by cross-linking the rubber compound from a linear macromolecule into a 3-dimensional network structure under certain temperature, pressure and time. It is usually insoluble in solvents.
