After Dow Corning's commercialization of silicone rubber Noun 1. silicone rubber - made from silicone elastomers; retains flexibility resilience and tensile strength over a wide temperature range synthetic rubber, rubber - any of various synthetic elastic materials whose properties resemble natural rubber  in 1942, we have seen the material improved both physically and economically to the point that it can now compete in traditional organic markets and imparts longer life to today's applications demanding greater reliability.

Silicone rubber is like a chameleon in nature. It may be seen, or it may be hidden within its natural surroundings. Silicone is used in just about every imaginable environment. And like the chameleon, it ensures its existence due to its unique chemical make-up.

Various forms of silicone physically touch our everyday life, from shampoo, surfactants in instant coffee, pharmaceutical tubing and automotive gaskets to fishing lures.

There is no other synthetic polymer Synthetic polymers are often referred to as "plastics", such as the well-known polyethylene and nylon. However, most of them can be classified in at least three main categories: thermoplastics, thermosets and elastomers.  available that can perform under such an extreme temperature range and retain its flexibility in application. Silicone's ability to be transparent physically is matched by its transparency in our everyday use of it. Silicone rubber's application is only hindered by the limits of one's imagination.

This article will provide a general overview of silicone rubber that may inspire one to change an existing application or create a new one using this versatile elastomer elastomer (?l?s`t?m?r), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. . We have gleaned and assimilated this information from a number of resources to provide germane germane .Being both pertinent and fitting. See Synonyms at relevant.

Terminology of silicones

Let's first look at some simple terminology regarding the metal from which the silicone is spawned and the various terms associated with silicone rubber.

* Silicon, Si (the metal);

* silicone rubber (general term);

* silicone gum (pure polymer);

* silicone R-gum or base (contains polymer and fillers for reinforcement);

* silicone compound (heat cured rubber [HCR HCR High Commissioner for Refugees (UN)

* liquid silicone rubber (LIM, LSR 1. (networking) LSR - Label Switching Router.

Silicone structure versus organics

Organics, i.e., NBR NBR Number

NBR National Board of Review , SBR SBR - Spectral Band Replication , IR and NR, are polymeric chains with carbon to carbon bonding that may have unsaturation present within the polymer chain. Silicones (figure 1) are formed via repeated alternating silicon to oxygen atoms and contain no unsaturation in their backbone. Unsaturation or a double bond in a organic polymer backbone (figure 2) is an area of chemical activity where vulcanization vulcanization (v?l'k?n?zā`sh?n), treatment of rubber to give it certain qualities, e.g., strength, elasticity, and resistance to solvents, and to render it impervious to moderate heat and cold.  can occur. At the same time, this area is prone to degradation by UV, ozone, corona and heat.
