The main chain of dimethyl silicone oil molecules is composed of silicon oxygen atoms, and the side groups connected to silicon are methyl groups. The viscosity range at 25℃ is 10~200 000mm2/s. Relative density d4200.93~0.975. Refractive index nD201.390～1.410. Colorless, transparent, non-toxic and odorless oil. It has excellent electrical insulation properties and heat resistance, high flash point and low freezing point, and can be used for a long time in the temperature range of -50 to +200°C. It has small viscosity-temperature coefficient, large compression ratio, small surface tension, good hydrophobicity and moisture resistance, and small specific heat capacity and thermal conductivity. It can be prepared by the telomerization reaction of dimethylcyclosiloxane and hexamethyldisiloxane in the presence of a catalyst. It is used as a release agent in the plastics and rubber industries; as a defoaming agent in the biochemical, pharmaceutical, and food industries; and as a shock-proof damping material in the machinery and instrument industries.
