Effect of vulcanization on rubber grommets | Rubber Grommets

Effects of extra-network materials in vulcanized rubber Natural rubber vulcanized with TMTD has good oxidation resistance. If zinc dimethyldithiocarbamate formed during the vulcanization period is extracted with acetone before oxidation, the oxidation resistance of the vulcanizate is no longer superior to that of a general sulfur accelerator vulcanized rubber.

What is vulcanised rubber?

Vulcanized rubber is stronger than non-vulcanized rubber because its bonds are made of cross-links at an atomic level.Charles Goodyear (1800-1860) - an American chemist, tried for years to use rubber in a variety of ways in his inventions, but was not successful in counteracting the poor thermal
