MCQ
Rubber is heated with sulphur and the process is known as:
- AGalvanization
- ✓Vulcanization
- CBessemerization
- DSulphonation
✓

Correct option: B.
Vulcanization
Natural Rubber is heated in the presence of sulphur. This produces cross$-$linking and leads to a harder material that is markedly more resistant to heat and relatively more elastic. This process is called vulcanization.
