Natural rubber is used extensively in many applications and products. In most of its useful forms, it has a large stretch ratio and high resilience, and is extremely waterproof. Natural rubber is also biodegradable.
Natural rubber is also called India rubber. Thailand and Indonesia are two of the leading rubber producers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. 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". The latex then is refined into rubber ready for commercial processing.
