Main characteristics:
Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity,physiological inertia and small surface tension. In addition, it also has low viscosity temperature coefficient and high
compression resistance). Some varieties also have radiation resistance. Silicone oil has many special properties, such as oxidation resistance, high flash point, low volatility, no corrosion to metal, non-toxic and so on.
Main purpose:
It is commonly used as high-grade lubricating oil, shockproof oil, insulating oil, defoaming agent, release agent,
polishing agent and vacuum diffusion pump oil. Among all kinds of silicone oil, methyl silicone oil is the most widely used and the most important variety in silicone oil, followed by methyl phenyl silicone oil. In addition, there are ethyl silicone oil,methyl phenyl silicone oil, nitrile containing silicone oil, etc. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
