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

3. Forms & CompositionsForms & 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
