Question

Explain vulcanization of rubber.

✓

Answer

Vulcanization of rubber:

The process by which a network of cross-links is introduced into an elastomer is called vulcanization.
Vulcanization of rubber is carried out to improve the physical properties of natural rubber.
The profound effect of vulcanization enhances the properties like tensile strength, stiffness, elasticity, toughness, etc. of natural rubber.
Most frequently the used process of vulcanization is sulfur vulcanization. Sulfur forms crosslinks between polyisoprene chains which results in improved properties of natural rubber.
