2. 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 costs and lower mechanical property values when compared to carbon based materials

3. Forms & Compositions
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

4. Silicone Products Caulking Breast implants Lubricants Adhesives
Sealants
Gaskets
Silly putty
Few thousand other forms
