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, small surface tension, non-corrosion to metal, non-toxic and so on. Because of these properties, silicone oils have excellent results in many applications. In all kinds of silicone oil, methyl silicone oil is the most widely used, is the most important variety of silicone oil.
Dimethyl silicone oil is the main part of industrial silicone oil. One of the most remarkable properties of linear polydimethylpolysiloxane is that it is a liquid that can flow over a very wide range of molar masses [from 162 g/mol (hmethydisiloxane) to 500,000 g/mol] and, correspondingly, has a wide range of viscosity. From 0.65 mm2/s(20oC) of hexamethyldisiloxane to a range that viscosity measurements cannot reach.
Dimethyl silicone emulsion is non-ionic, good stability, non-flammable, non-volatile, non-toxic and odorless, high temperature resistance, corrosion resistance, oxidation resistance, can be diluted with water in any proportion and other advantages. Using dimethyl silicone oil as raw material, the emulsion can be used in textile finishing to improve the smooth and soft feel of the fabric. Used in the daily care products shampoo can improve the lubrication of hair; Used in the treatment of rayon spinning head, can eliminate static electricity, improve the quality of wire drawing; Used in cosmetics, cosmetics can improve the skin moisture and protection. In addition, dimethyl silicone oil emulsion can also be widely used in rubber, cosmetics, textiles, demoulding, leather and other industries, can play a role in waterproof, lubrication, demoulding and other aspects (defoaming agent, demoulding agent, polishing agent, isolator).
