The term silicone was coined by Frederick Kipping, who pioneered the study of the organic compounds of silicon. Silicones are nonstick, rubber-like and heat-resistant compounds commonly used in lubricants, adhesives, cookware, insulation, sealants, medical applications, and breast implants. They are very stable and resist the effects of heat, water and oxidizing agents. Silicones are any of a diverse class of elastomers, fluids or resins based on polymerized siloxanes, substances whose molecules consist of chains made of alternating silicon and oxygen atoms. http://cadmodels.org/?q=silicone
