Answer 1

Answer:

The non metal used to treat rubber in the process of Vulcanistaion is Sulphur.

Explanation:

The nonmetal used to treat rubber in the process of vulcanization is sulphur. Natural rubber is soft, sticky and has less tensile strength. Vulcanization makes rubber more strong, tough and elastic. Natural rubber is mixed with 3 to 5 % sulphur  and heated at 100 to 150 deg C, which results in cross linking of chains of cis-1,4-polyisoprene through disulphide  (−S−S−) bonds.
