◆Dimethicone, chemical name polydimethylsiloxane
Dimethicone is a colorless and transparent synthetic polymer material with a variety of different viscosities (5cps to 2 million cps), from easy-flowing liquids to thick semi-solids. This product has smoothness, softness, hydrophobicity, good chemical stability, electrical insulation and high and low temperature resistance. High flash point, low freezing point, can be used for a long time at -50℃～+200℃, small viscosity-temperature coefficient, high compressibility, low surface tension, good water repellency and moisture resistance, and low specific thermal conductivity.
Since dimethicone has a variety of uses, it can be used in different industries, mainly including:
◆In the daily chemical industry, it is used in various cosmetic formulations such as skin care cream, body wash, shampoo, etc., with a soft effect and silky feel.
◆Rubber, plastic, latex, polyurethane, light industry and other industries: used as release agent, release agent and brightener in the production of certain rubber, plastic, latex, polyurethane products and handicrafts.
◆It is used as lubricating oil, liquid spring, cutting fluid, buffer oil, transformer oil, high and low temperature brake oil, brake oil, instrument shock absorption oil, frame molding release agent, etc. in machinery, automobile, instrument, electronic appliance and other industries. .
◆It can be used as softener, water repellent, feel improver, sewing thread lubrication, chemical fiber spinneret lubrication and garment lining auxiliaries in textile and garment industries.
◆In leather and leather chemical industry, this product can be used as softener, water repellent, hand feeling agent, defoamer, brightener, etc. by adding this product to other additives.
◆It is used as defoamer, lubricant, weather-resistant coating in chemical, paint and building materials industries.
◆Used for other specific purposes, or copolymerized with other materials to form new materials.
◆Depending on the specific application object and application environment, the dosage ranges from a few PPM to more than 99%.
Dimethicone has a tendency to degrade and volatilize in contact with high-concentration strong acids or alkalis and Lewis acids. The higher the temperature, the more obvious the reaction. When a low concentration of strong acid or strong base is in contact with it or under the action of high temperature for a long time, the viscosity tends to increase until cross-linking.
