Polydimethylsiloxane chemical stateDimethyl silicone oil, colorless or light yellow liquid, odorless, hightransparency, with heat resistance, cold resistance, viscosity with temperaturechange is small, waterproof, surface tension is small, with thermalconductivity, thermal conductivity of 0.134-0.159W / M * K, light transmittanceof 100%, dimethyl Silicone oil non-toxic and tasteless, with physiologicalinertia, good chemical stability. Electrical insulation and weatherability,hydrophobic, and has a high shear capacity, can be in the -50 ℃ ~ 200 ℃ underlong-term use. It has excellent physical properties and can be directly used ininsulation, damping, damping, defoaming, lubrication, polishing and so on. Itis widely used as insulating lubrication, shockproof, oil dust, dielectricfluid and heat carrier. As well as for defoaming, release agent, paint anddaily chemicals additives.
Polydimethylsiloxane can be used as anemulsion base in admixture with lanolin, stearyl alcohol, cetyl alcohol,glyceryl monostearate, Tween, Span and other surfactants. In this product byadding thin-film forming agent such as PVP, PVA and cellulose derivatives,etc., can enhance its protection.
