Crystalline density at 25 o C: … WebSilicones are synthetic polymers with a silicon-oxygen backbone similar to that in silicon dioxide (silica), but with organic groups attached to the silicon atoms by C-Si bonds. The silicone chain exposes organic groups to the outside. Thus, despite having a very polar chain, the physical properties of silicones are similar to those of an alkane.
