1. Linear silicones – They are obtained by the hydrolysis and subsequent condensation of dialkyl or diaryl silicon chlorides.
- Silicone rubbers – These silicones are bridged together by methylene or similar groups.
- Silicone resins – They are obtained by blending silicones with organic resins such as acrylic esters.
2. Cyclic silicones – These are obtained by the hydrolysis of R2SiCl2 .
3. Cross linked silicones – They are obtained by hydrolysis of RSiClr
