What are Silicones?What are Silicones? are synthetic polymers with a linear, repeating silicon-

oxygen backbone Silicone polymers do not have carbon as part of the

backbone structure Have a high melting and boiling point Depending on the number of repeat units in the polymer

chain and the degree of cross-linking, six classes of commercially important products can be produced

Some disadvantages of Silicone are increased costsand lower mechanical property values when compared to carbon based materials

Fluids, Emulsions, Compounds, Lubricants, Resins and rubbers

Varies from liquid to gel, or rubber to hard plastic odorless and colorless, water resistant, chemical resistant,

oxidation resistant, stable at high temperature, and have weak forces of attraction, low surface tension, low freezing points and do not conduct electricity

seem to be impervious to the effects of aging, weather, sunlight, moisture, heat, cold, and some chemical assaults
