Polydimethylsiloxane, also known as dimethylsilicone oil, according to the relative molecular weight of different, the appearance of colorless transparent volatile liquid extremely high viscosity liquid or silica gel, odorless, high transparency, heat resistance, cold resistance, viscosity changes with temperature, water resistance, surface tension is small, with thermal conductivity, thermal conductivity of 0.134-0.159W/(m·K), Light transmittance of 100%, dimethylsilicone oil is non-toxic and tasteless, with physiological inertia, good chemical stability. Electrical insulation and weather resistance, good hydrophobicity, and has a high shear resistance, can be used at -50℃ ~ 200℃ for a long time. With excellent physical properties, it can be directly used for moisture-proof insulation, damping, shock absorption, defoaming, lubrication, polishing, etc. It is widely used as insulation lubrication, shock proof, oil dust proof, dielectric fluid and heat carrier. And used as defoaming, release agent, paint and daily chemical additives.
application:
The combination of low cosmetic application, surface tension, easy to spread, and suitable viscosity gives personal care products a lubricated, greasy feeling and makes the skin soft. It has the function of suppressing foam, defoaming and anti-foaming to prevent the "whitening" phenomenon when applying the product. Different products need to choose different viscosity, the higher the viscosity, the more oily, the lower the viscosity gives the skin a dry feeling. Due to its deposition, it is used in low quantities in cosmetic formulations. The characteristics of the product can be adjusted by using polydimethylsiloxanes with different viscosity grades.
Electrical products polydimethylsiloxane, can be used for electronic connectors in electrical and electronic industry. Leather products polydimethylsiloxane, can be used for fiber, leather: hydrophobic agent, softening agent, feel improver, dyeing industry defoamer, sewing thread lubrication. The emulsion can be applied to the fatening of leather, thereby enhancing the hydrophobicity, softness and comfort of leather. It is used to treat leather surfaces to enhance wear resistance, water resistance and mold release. Brightener polydimethylsiloxane, suitable for use as brightener ingredients for automobiles, furniture, footwear, cement products, etc., including automotive brightener, foam furniture cleaner, ethylene roof cleaner, building materials bright formula, with the least amount can achieve the best results.
Release agent polydimethylsiloxane, can be used as rubber or plastic products (brake, screw, plug, etc.), EVA shoe material release agent, directly or dilute 10-200 times with low hardness water, the product is efficient, stable, and widely used. Lubricant polydimethylsiloxane, a lubricant used in extruding rubber products such as conveyor belts. It can be used as a lubricant for the following textile processes: yarn weaving, sewing thread lubrication, sock and underwear production, sewing needle lubrication, glass fiber filter.
