Question

The percentage of sulphur used for vulcanisation of natural rubber for making tyres and battery case are respectively.

Answer 1

For tyres is 3 to 5%

And for battery case is 30%

Answer 2

Answer:

The Correct Answer would be 4% - 5% and 29% - 30%.  4% - 5% of the element Sulphur is usually used for vulcanization of natural rubber that in result is used for making tyres as well as 29% - 30% is used for making battery case.

Explanation:

What is meant by Vulcanization?

Vulcanization is basically a process in which natural rubber is mixed as well as treated with the element Sulphur and some important organic compounds that are used to accelerate or to increase the speed of reaction that is taking place between the rubber and Sulphur. It is useful in introducing Sulphur bridge between polymer chains and hence, very useful in increasing Sulphur's tensile strength, resistance to abrasion elasticity, etc
