Property and Application:

250-30: low viscosity, low freezing point, good heat resistivity, high flash point, low expansion coefficient, excellent electrical insulation property. Used as insulation impregnating agent for large scale power condenser and separation and anti-adherent for blood bag and transfusion bag, basic oil for surgical medicines, cosmetics and oil additives for skin-care, chilblain preventive agents.

255: it has the general properties of methyl silicone oil, with better heat resistivity, excellent anti-oxidizing ,lubricating ,and anti-radiation properties, lower freezing point and stability to water, used in insulation, lubrication,damping, anti-shock,dustproofing, and as high temp. thermal carrier.

275: very low saturated vapor pressure, good heat resistivity and excellent anti-oxidizing property, used in high vacuum. Industry, high vacuum. Coating for electronics, particle accelerator, electronic microscope and display, etc.
