While sulfur is the most common curing medium used in vulcanization, other chemicals used in the process include:.

Countless rubber products and objects are vulcanized, some of which include O-rings, gaskets, seals and even tires. ScienceDirect explains that vulcanization changes the physical properties of rubber by forcing it to retract.

Of course, there are mechanical methods that can force rubber to retract as well. The difference with vulcanization, however, is that it retains the original shape of the rubber. When vulcanization is performed on rubber, the rubber shrinks while retaining its original shape.

Vulcanization essentially scales down rubber to a smaller size, all without deforming or altering its shape. In addition to altering its size while retaining its shape, vulcanization also protects rubber from future deformation.

Rubber also becomes harder when vulcanized, which subsequently increases its tensile strength and reduces the risk of physical damage. Unlike with thermoplastic chemical processes, the effects of vulcanization are permanent.

While its highly conductive The amount of sulphur present determines the hardness of the cured product, and the addition of other chemicals and fillers can further enhance the eventual properties of the finished rubber item.

The process that generally came to be known as vulcanisation throughout the world has of course been extensively developed, and is now the global science and industry that is rubber compounding.

The traditional sulphur cure system developed all those years ago by Goodyear was just the beginning of what has become a vast selection of different polymer families including synthetic materials, allied to a vast range of curatives, process aids and fillers.

These can be combined in an infinite number of ways to deliver tailored and specific performance from the fascinating group of materials collectively known as rubber, yet it all goes back to the accidental discovery that Goodyear had that day in his laboratory, and his curiosity as to the unexpected change that had occurred. Without that, so many technological developments that we take for granted would never have happened; think about that as you drive along on your vulcanised natural rubber tyre treads…..
