Silicone

A non-metallic material typically made from four elements: silicon, oxygen, hydrogen and carbon. It can be in a thermosetting elastomer or liquid form. The thermosetting elastomer form is noted for high heat resistance. They are polymeric materials in which the recurring chemical group contains silicon and oxygen atoms as links in the main chain. Various organic groups are attached to the silicon atoms and enhance performance of the silicone polymer. Methyl groups are most common and provide good heat and UV resistance, phenyl groups provide low temperature resistance, while fluorine containing groups provide fuel and non-polar solvent resistance. Silicone rubber extrusions offer retention of good electrical properties, resilience and flexibility after long-time heat aging.
