Question
Attempt the following:
Explain the vulcanisation of rubber. Which vulcanizing agents are used for the following synthetic rubber?
a. Neoprene
b. Buna-N
Advertisements
Solution
The process by which a network of cross-links is introduced into an elastomer is called vulcanization. The profound effect of vulcanization enhances the properties like tensile strength, stiffness, elasticity, toughness; etc. of natural rubber.
a. Neoprene: MgO is used to vulcanize neoprene.
b. Buna-N: Sulfur is used to vulcanize Buna-N.
