Natural rubber , also called  India rubber  or  caoutchouc , as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Malaysia and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. 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. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for marketing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch

Injection molding of liquid silicone rubber  (LSR) is a process to produce pliable, durable parts in high volume. Liquid silicone rubber  is a high purity platinum cured  silicone  with low compression set, great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is a must. Due to the  thermosetting  nature of the material, liquid silicone  injection molding  requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and  vulcanized . Chemically, silicone rubber is a family of  thermoset elastomers  that have a backbone of alternating silicon and oxygen atoms and  methyl  or  vinyl  side groups. Silicone rubbers constitute about 30% of the silicone family, making them the largest group of that family. Silicone rubbers maintain their mechanical properties over a wide range of temperatures and the pre

Both rubber and silicone are elastomers. They are polymeric materials that exhibit the viscoelastic behavior, which is generally called elasticity. Silicone can be distinguished from rubbers by the atomic structure. In addition, silicones have more special properties than normal rubbers. Rubbers are naturally occurring, or they can be synthesized. Based on this, silicone can be differentiated from rubber.  Rubber Generally, all the elastomers are considered as rubbers in which dimensions can be changed largely by stressing, and can be returned to the original dimensions after removing the stress. These materials show a glass transition temperature due to their amorphous structure. There are many types of rubbers or elastomers like natural rubber, synthetic poly isoprene, styrene butadiene rubber, nitrile rubber, polychloprene, and silicone. But natural rubber is the rubber which comes to our mind when considering rubbers. Natural rubber is obtained from the latex of Heveabrasilien
