Hydroxy silicone oil, also known as dimethyl hydroxy silicone oil, has a structural formula of HO[(CH3)2SiO]nH. It is a linear polymer with repeated silicon-oxygen bonds as the main chain, methyl groups as side groups, and hydroxyl groups. This silicone oil is colorless, transparent, tasteless and odorless. Soluble in carbon tetrachloride, benzene, chloroform, ether, toluene and other organic solvents, insoluble in water and ethanol, low viscosity hydroxy silicone oil has a certain solubility in water. It can be used in the manufacture of silicone hydroxyl emulsion as a fabric, paper and leather treatment agent. Dimethyl hydroxy silicone oil is widely used as a structure control agent in the processing of silicone rubber. It can effectively control the structural interaction between the compound rubber and white carbon black, improve the processing performance of silicone rubber, and prolong the storage period of the rubber compound. Dimethyl hydroxy silicone oil can also be used as an intermediate in the synthesis of various polysiloxanes

Application field
Low molecular weight hydroxy silicone oil is often used in the preparation of block polymers and defoamers. It is widely used in the silicone rubber product industry. It is an excellent structure control agent commonly used in silicone rubber processing. It can improve the processing performance of silicone rubber, prolong the storage period of rubber materials, increase the transparency of rubber products, and improve the mechanical properties of silicone rubber. It is also used to prepare cationic, anionic, and nonionic hydroxyl silicone oil emulsions (hydroxyemulsion), and used together with hydrogen-containing silicone oil. It is an excellent treatment agent for fabrics, leather, and paper.
High molecular weight hydroxy silicone oil is mainly used as the base compound of room temperature vulcanized silicone rubber, and various silicone rubber products made of it are resistant to high and low temperature, oxidation resistance, and have excellent electrical insulation properties. Widely used in electronics, electrical appliances, national defense cutting-edge technology fields and other industrial sectors.
