Silicone Elastomeric and Silicone Rubber Materials. Silicone elastomers or silicone elastomerics most often refers to silicone-based polymers that have been vulcanized. Silicone rubber is an elastomer (rubber-like material) composed of silicone —itself a polymer —containing silicon together with carbon, hydrogen, and oxygen.
Silicone caulk can be used as a basic sealant against water and air penetration. Silicones are polymers that include any inert, synthetic compound made up of repeating units of siloxane, which is a functional group of two silicon atoms and one oxygen atom frequently combined with carbon and/ or hydrogen. They are typically heat-resistant and rubber-like, and are used in sealants, adhesives, lubricants, medicine, cooking utensils, and thermal and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk. Silicone, the product, may be a liquid lubricant, a semi-solid adhesive or a rubber-like plastic polymer. Liquid silicone is often used as a lubricant. An example of a thicker form of rubberized silicone would waterproof sealant used in bathrooms and window fitting. Silicone rubber is a silicon polymer with rubberized qualities. It was first produced under the chemical name of polydimethlysiloxane. Silicone rubber is heat resistant so can be used to make cookware including oven mitts, tongs, pot holders and pan handles. Silicone rubbers are often one-or two-part polymers, and may contain fillers to improve properties or reduce cost. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -55 °C to +300 °C while still maintaining its useful properties. Acetoxy tin condensation is one of the oldest cure chemistries used for curing silicone rubber, and is the one used in household bathroom caulk. The smell of vinegar in the form of acetic acid is the usual indicator that the reaction is incomplete. silicones having rubberlike properties. Industrial silicone elastomers are of the polyorganosiloxane type. The macromolecules of silicone elastomers have the structure. where R and R’ are alkyl, alkenyl, or aryl and R” is hydrogen, an alkyl, or —Si(R) 3. The main industrial silicone elastomers are thermostable dimethylmethylvinylsiloxanes (Soviet brand name, SKTV). Silicone rubber is an elastomer (rubber-like material) composed of silicone —itself a polymer —containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Acetoxy tin condensation is one of the oldest cure chemistries used for curing silicone rubber, and is the one used in household bathroom caulk. The smell of vinegar in the form of acetic acid is the usual indicator that the reaction is incomplete. silicone elastomers, for example. An elastomer is a polymer that shows elastic properties. Since the terms rubber-like and elastomeric mean almost the same thing, the terms “rubber” and “elastomer” are often used interchangeably today to describe silicone elastomers. Rubber vs Silicone. 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 Choose silicone rubber – the material that works for you. Silicone rubber is an inorganic synthetic elastomer made from a crosslinked silicon-based polymer reinforced with filler. It offers a unique combination of chemical and mechanical properties organic elastomers cannot match.  Silicone Elastomer, Silicone Elastomeric and Silicone Rubber Materials. Silicone elastomers or silicone elastomerics most often refers to silicone-based polymers that have been vulcanized. Albeit technically incorrect, the term silicone rubber is often used since it is more intuitive and descriptive. Silicone elastomers or silicone rubber materials are readily available in a variety of forms, such as solids, open cell foams, closed cell sponges, thermally conductive, and electrically conductive. Now, silicone elastomer materials are used in place of rubber in almost all work done by Stockwell Elastomerics, which was renamed in 2005 to reflect the emphasis on silicone elastomer materials.
