Vulcanisation of rubber decreases its__________________?
Correct answer: A. Tackiness
- A. Tackiness
- B. Resistance to organic solvents
- C. Tensile strength
- D. Working temperature range
Explanation
Vulcanisation forms sulphur cross-links between rubber chains, reducing chain slippage and surface stickiness. It generally increases tensile strength and solvent resistance rather than decreasing them.
