Introduction to Hydroxyl Terminated Silicone Oil

Chemical nameHydroxyl Terminated Silicone Oil

CAS No.: 70131-67-8

HS Code: 3910000000

Molecular FormulaHO[(CH3)2SiO]nH

EINECS: 213-915-7

AppearanceColorless oily liquid

Hydroxyl silicone oil is an oily silicone liquid of linear polydimethylsiloxane with hydroxyl end group. It has the characteristics of methyl silicone oil. Low viscosity hydroxyl silicone oil is an excellent good structure control agent in silicone rubber processing, which can replace diphenyl silyl glycol, simplify the process and improve the process performance. It is also used as a waterproof, soft and anti-sticking agent for fabrics, leather and paper. We provide customization & Free Sample of our hydroxyl terminated silicone oil.

Performance and Application

It is colorless or nearly colorless oily liquid. It dissolves in carbon tetrachloride,

benzene, chloroform, ether, toluene and other organic solvents & is insoluble in water and ethanol. Low-viscosity hydroxyl silicone oil has solubility in water. It can be used as treatment agent for fabric & paper. It is widely used as structure control agent in silicone rubber processing. It can control the structural effect between rubber mix and white carbon black, improve processing performance of silicone rubber, and extend storage period of rubber compounds. Dimethyl hydroxyl silicone oil can also be used as intermediate for synthesis of various polysiloxanes.
