Silicone oil has many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, non-corrosion to metals, non-toxic, etc. Because of these characteristics, silicone oil has excellent effects in many applications. Among various silicone oils, methyl silicone oil is the most widely used and is the most important variety in silicone oil.
Dimethicone is the main body of industrial silicone oil. One of the most remarkable characteristics of linear polydimethyl silicone oil is that it is a flowing liquid in a very wide range of molar masses [from 162 g/mol (hexamethyldisiloxane) to 500000 g/mol]. The viscosity range is also very wide, from 0.65 mm2/s (20oC) of hexamethyldisiloxane to the range that cannot be reached by the viscosity measurement method.
The dimethyl silicone oil emulsion is non-ionic, with good stability, non-flammable, non-volatile, non-toxic and odorless, high temperature resistance, corrosion resistance, oxidation resistance, and can be diluted with water in any proportion. The emulsion uses dimethyl silicone oil as the raw material. After being emulsified, it can improve the smoothness and softness of the fabric when used in the finishing of textiles; it can improve the lubricity of the hair when used in shampoos for daily care products; it can be used to treat rayon spinning heads. It can eliminate static electricity and improve the quality of spinning; when used in cosmetics, it can improve the moisturizing and protective effects of cosmetics on the skin. In addition, dimethyl silicone oil emulsion can also be widely used in rubber, cosmetics, textile, mold release, leather and other industries, and can play a role in waterproof, lubricating, and mold release (defoaming agent, mold release agent, polishing agent) , Release agent).
