What is Vulcanization of Rubber?

The process transforms elastomers with weak thermoplastic properties into a strong, elastic and tough substance with useful properties and introduces a network of cross links into the elastomers. Tensile strength is maximum at optimum cure. Beyond this point, the stock is said to be over cured. It gets stiffer and harder but weaker and less extensible. Techniques of Vulcanization Vulcanisation can be carried out using several techniques. Compression Moulding – This is the most common method used in the industry. Here the blank is placed in a two piece mould, one…
