Process Of Making Natural Rubber

Processing natural rubber consists of the following steps.

Process of making natural rubber.

1 mastication when the elastomer is sheared and the molecules are broken down to give easier flow 2 mixing usually carried out immediately after mastication when additives are incorporated 3 shaping of the viscous mass for example by extrusion or molding and 4 curing when the polymer molecules become. Transfer molding is a natural progression in development to limit the disadvantages of compression molding. Compounding mixing molding and casting and finally vulcanization. Types of polyisoprene that are used as natural rubbers are classified as elastomers.

It takes several quite distinct steps to make a product out of natural rubber. That involves making a wide v shaped cut in the tree s bark. Synthetic rubber derives from molecular polymers. Natural rubber comes from latex.

Whether natural or synthetic rubber continues through four steps. Natural rubber also called india rubber latex amazonian rubber caucho or caoutchouc as initially produced consists of polymers of the organic compound isoprene with minor impurities of other organic compounds plus water thailand and indonesia are two of the leading rubber producers. In this beginning stage pre heating takes place in the rubber forcing the rubber to flow through channels. International rubber study group.

At approximately 2 321 per ton the natural rubber market involved about 22 5 billion in 2007 source. Rubber processing consists of four basic steps. The rubber production process begins with natural or synthetic rubber. As the latex drips out it s collected in a cup.

First you have to gather your latex from the rubber trees using a traditional process called rubber tapping.
