Natural Rubber Sheet Processing

Contrast this with synthetic rubber production.

Natural rubber sheet processing.

Natural rubber sheeting is one such by product. Natural rubber latex is traditionally converted into sheet form through careful coagulation and subsequent milling process on two roll mills. The sheets are then baled together and with talc to separate them and keep them from sticking to each other. Natural rubber also called india rubber or caoutchouc as initially produced consists of polymers of the organic compound isoprene with minor impurities o.

After inspection any imperfections that are found by the natural rubber sheet suppliers are removed. It combines botany chemistry and sophisticated machinery with dexterous skills of the people who harvest the trees. Companies begin by obtaining the latex fluid which means tapping the sap from the rubber trees filtering the latex and then packaging it in drums for export or processing. Processing of natural rubber involves the addition of a dilute acid such as formic acid.

The most important forms in which nr is processed are the following. Natural rubber nr is produced from latex obtained from rubber trees in plantations. The coagulated rubber is then rolled to remove excess water. They make smoked sheets of latex rubber.

Currently rubber is harvested in the form of the latex from the rubber tree or others like oak and pine. Growing and processing natural rubber is one of the most complex agricultural industries and requires several years. Sheets crepes block rubber and preserved latex concentrates. The latex then is refined into rubber that is ready for commercial processing.

Rolling the latex into thin sheets. The latex is a sticky milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called tapping. There are many types of sheets rubbers namely ribbed smoked sheet rubber air dried sheet tuber and sun dried sheet rubber depending on the drying methodology used.
