Natural rubber, also called India Rubber or Caoutchouc, is a mixture of organic compound polyisoprene and small amounts of other organic compounds as well as water. This polymer is the main component. This material is classified as an elastomer (an elastic polymer). It is derived from latex, a milky colloid produced by some plants. The plants are ‘tapped’, that is, an incision made into the bark of the tree and the sticky, milk colored latex sap collected and refined into a usable rubber. Polyisoprene can also be produced synthetically. Natural rubber is used extensively in many applications and products, as is synthetic rubber. It is normally very stretchy and flexible and extremely waterproof.

Him with the platitudes and rubber doughnuts,
Melting at the knees, a varicose horror.

Have you come to unhinge my shadow?”
