5000cst Silicone Oil

Silicone oil, is a hydrophobic organic silicon material. There is a use in various fields such as drugs, daily compounds, food, and buildings. Its derivatives have reached hundreds, and commonly used polysiloxanes are mainly: polydimethylsiloxane, cyclosiloxane. , Aminosiloxane, polymethylphenylsiloxane, polyether polysiloxane copolymer, and the like. Wherein, the loop polymethylsiloxane is a commonly used polysiloxane.

3.Mainly used

Dimethyl silicone oil is inertless, has physiological inert, good chemical stability, electrode and weather resistance, wide viscosity, low solidification points, high lightning, good hydrophobic performance, can be Long-term use within 50 ~ 180 ° C, widely used to do insulation, lubrication, shockproof, dust oil, dielectric fluid, and heat carrier, additives for antifoaming, disengagement, paint and daily cosmetics, etc.
The dimethyl silicone oil has a variety of excellent features, so it has been extremely widely used in industrial and agricultural production departments, national defense industries, scientific research and health care. It is widely used in electrical insulation, demolding, defoaming, damping, shockproof, rolling, dustproof, waterproof, high and low moist.
  • In the automotive industry and the aviation industry, it can also be used as hydraulic oil, shock absorbing oil, brake oil, etc.
  • Use it in textile to reduce friction, prevent hair, and break.
  • Non-stick with rubber, plastic, etc., can be used in various rubber, plastic molding processed release agents.
  • Due to the small tension of the silicone oil, the antifoaming agent of the industry can be used.
  • Silicon oil on the motor, electrical, electronic instrument can improve the moisture-proof insulation.
  • Other item additives such as paint, ink, polished oil can also be made.
  • Add it in cosmetics to improve moisturizing and protective effects on skin, and so on.

4. Package and storage:
Package by 25kgs/50kgs/200kg drum.
It could be stored well for a long time by avoiding directly to contract with moist environment.
