The Birth of the Modern Condom | HowStuffWorks
But it wasn't until Charles Goodyear discovered vulcanization in 1839 that rubber took its place in contraceptive history. Straight from the Hevea brasiliensis tree, liquid rubber, or latex, turns into a substance that's bouncy but brittle. Goodyear used sulfur and lead oxide to strengthen the bonds between the rubber's molecules, which made it stronger, more elastic and less likely to break down over time.

Material Matters: Vulcanised Rubber Sole Construction
The original method of vulcanisation, and still the most common, is to mix sulphur with natural rubber and then heat it. The sulphur changes the chemical structure of the rubber, creating crosslinks between polymers to make them stronger and more durable.

Vulcanization primer: The importance of vulcanized rubber
Vulcanized rubber was the answer. This material could be precisely formed, would deform under pressure and then quickly recover. These qualities, as well as durability and lack of stickiness, made vulcanized rubber the ideal sealing material. Vulcanized o-rings. Budlar Flexible Products offers custom vulcanized o-rings in a wide variety of compounds. They include Aflas, Buna White FDA, EPDM, neoprene, silicone and Viton.

Vulcanization
Vulcanization is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber using metal oxides. Vulcanization can therefore be defined as the curing of elastomers; with the terms

Sulfur Vulcanization
Sulfur Vulcanization of Rubbers (polydienes) Vulcanization of rubber by sulfur alone is extremely slow and can take several hours at elevated temperatures (140°C or more). This is problematic because long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties.
