Linear polymers, reinforcing agents, a crosslinker, and a catalyst are used to create Silicone Elastomers. Heat Cured Rubber (HCR), Liquid Silicone Rubber (LSR), and Room Temperature Vulcanization are three different types of elastomers that are formed depending on the viscosity and type of the fundamental straight-chain molecule and the processing temperature (RTV). Depending on the technology selected to suit exact processing requirements, radical, condensation, or addition crosslinking processes may be used.
To assure certain properties (color, rheology, pot life, etc.) or performance standards, a wide range of additives can be added to the elastomer in its final composition (electrical insulation or conduction, heat transfer, fire retardancy, chemical adhesion, mold release, etc.). Mineral fillers, such as silica, alumina, calcium carbonate, silicone resins, etc., can be used to reinforce these elastomers. To create Silicone Elastomers with good mechanical properties, reactive, straight-chained molecules are combined with a cross-linking agent and reinforcing (elasticity, absorption, tear strength).
