What is Polydimethylsiloxane?

Polydimethylsiloxane is a hydrophobic silicone material. It is used in various fields such as pharmaceuticals, daily chemical products, food, construction, etc. Its derivatives have reached hundreds of kinds. The commonly used polysiloxanes mainly include: polydimethylsiloxane, cyclomethicone. , aminosilicone, polymethylphenylsiloxane, polyether polysiloxane copolymer. Among them, cyclomethicone is a commonly used polysiloxane.

Polydimethylsiloxane chemical state dimethyl silicone oil, colorless or light yellow liquid, odorless, high transparency, heat resistance, cold resistance, viscosity change with temperature, water resistance, surface tension, heat conduction The thermal conductivity is 0.134-0.159W/M*K, and the light transmittance is 100%. The dimethyl silicone oil is non-toxic and tasteless, and has physiological inertness and good chemical stability. It has good electrical insulation and weather resistance, good hydrophobicity, and high shear resistance. It can be used for a long time at -50 °C ~ 200 °C. It has excellent physical properties and can be directly used for moisture insulation, damping, shock absorption, defoaming, lubrication, polishing, etc. It is widely used as insulation lubrication, shockproof, dustproof, dielectric fluid and heat carrier. And used as defoaming, release agent, paint and daily chemical additives.
