The viscosity of silicone oil is distinguished from the surface by the different flow properties, and the fluidity of different viscosities is different. The viscosity of silica gel is from 0.65cst to 100w cst, but the performance is different. The low viscosity is dangerous and can burn, but usually the viscosity is very stable and chemically inert. 50cst, 100cst, 350cst, 500cst, 1000cst are the usual viscosities of 50-1000.

Silicone oil has excellent heat resistance, oxidation resistance and low temperature resistance, and can be used for a long time in the temperature range of -50℃-+180℃; strong shear resistance, more than 20 times the compressibility of general mineral oil, is ideal liquid spring; low temperature and viscosity coefficient, low vapor pressure, low surface tension, good water enhancement and lubricity; excellent electrical properties, high breakdown voltage resistance, arc resistance, corona resistance, low dielectric loss; also has It has the advantages of good light transmittance and non-toxic effect on human body.

Silicone oil is generally used on the wire. Because it has the function of cooling, it can prevent thread breakage, skip stitches, and can also wipe the adhesive tape. According to its density, it is graded. The sewing machine oil is based on refined mineral oil. A lubricating oil prepared with anti-oxidant and anti-rust additives. It is suitable for various parts in industrial sewing machines such as cams, sliders, gears, bearings to provide excellent lubrication and meet the main application requirements such as color stability and rust prevention. Now white and easy to clean.

The viscosity of silicone oil will affect many properties of silicone oil, such as flash point, refractive index, viscosity-temperature coefficient, etc.
