Molecular formula: (R2SiO)x
Properties: Polymers containing Si-O-Si bonds to form the main chain structure. Customarily known as silicone or polysilicon ether, it can be linear,
According to the application of the product is classified into three categories: silicone oil, silicone rubber and silicone resin.
The raw material for synthesizing siloxane is a derivative of silane SinH2n+2. Hydrolysis of R2SiCl2 type organochlorosilanes can give linear siloxanes and cyclic siloxanes. With R2SiCl2 and RSiCl3 type organochlorosilane hydrolysis, condensation poly crosslinked siloxane.
Silicones are stable to heat and chemical agents, are not wetted by water, have outstanding aging resistance, excellent hydrophobicity and electrical insulation. Used as fire retardant, lubricant, moisture-proof agent. Silicone is used to make fiber reinforced materials. Silicone rubber is also used in adhesives and sealing materials.
