____________________ of rubber decreases after its vulcanisation?
Correct answer: A. Tackiness
- A. Tackiness
- B. Resistance to the action of organic solvent
- C. Maximum service temperature
- D. Tensile strength
Explanation
Vulcanisation forms sulphur cross-links between rubber chains, reducing their stickiness or tackiness. It generally increases tensile strength, solvent resistance, and usable temperature range.
