silicone   (sĭl'ĭ-kōn')  Pronunciation Key 
Any of a class of chemical compounds consisting of long chains of alternating silicon and oxygen atoms, with two organic radicals, typically a methyl (CH3) and a phenyl (C6H5) group, attached to each silicon atom. Silicones are very stable and resist the effects of water, heat, and oxidizing agents. They are used to make adhesives, lubricants and synthetic rubber.
