Vulcanization is a chemical process for converting natural rubber into more durable materials by adding:
Correct answer: A. Sulfur
- A. Sulfur
- B. Chlorine
- C. Oxygen
- D. Carbon black
Explanation
Vulcanization involves heating natural rubber with sulfur. This process creates cross-links between the long polymer chains of the rubber, which dramatically improves its elasticity, strength, and resistance to temperature changes.
