What is Vulcanization?
Vulcanization of Rubber
Rubber Standards. ASTM's rubber standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and .
Vulcanization is a chemical process that significantly enhances the properties of rubber. This process involves adding a vulcanizing agent, usually sulfur, to the raw rubber. During vulcanization, the agent causes the rubber’s chains to form . Discovered by American chemist Charles Goodyear in 1839, vulcanization is a chemical process that transformed the rubber industry. The technique, which involves .

Conversely, when rubber is subjected to a constant stress, an increase in the deformation takes place with time; this behaviour is called “creep”. Tests in compression are normally made under continuous stress conditions (i.e. the test piece remains strained throughout the test), and are hence a measure of sealing force.This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Testing and analysis.

A Beginner's Guide to Rubber: Rubber Vulcanization There are many ways to form rubber parts, part 3 of this guide will discuss the remaining more popular processes used in the industry today. As mentioned earlier, the process for turning rubber compounds into usable finished products is vulcanization. Discovered by American chemist Charles Goodyear in 1839, vulcanization is a chemical process that transformed the rubber industry. The technique, which involves combining rubber with other materials, turns natural rubber into a durable, elastic material with many practical applications. Another term for vulcanization is “cure”.
