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
