What happens to rubber after vulcanisation

What kinds of modifications to rubber's structure and properties often take place after vulcanization?

 

 

1. Vulcanized rubber develops a three-dimensional mesh structure rather than a linear one;

2. heating stops flowing;

3. not soluble in its suitable solvent anymore;

4. Hardness and modulus rise;

5. enhanced mechanical characteristics;

6. increased chemical stability and ageing resistance;

7. Media assets might get worse.

 

The role of vulcanisation accelerators:

 

 

Improves the productivity of rubber products by reducing costs and improving performance. Can promote the vulcanization of substances. Can shorten the vulcanisation time, reduce the vulcanisation temperature, reduce the amount of vulcanising agent and improve the physical and mechanical properties of rubber.
