Question
Explain vulcanization of rubber.
Advertisements
Solution
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.
