3.Mainly used

Dimethyl silicone oil is inertness, 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.
  • In the automotive industry and aviation industry, silicone oil can also be used as hydraulic oil, shock absorption oil, brake oil, etc.
  • The use of silicone oil in spinning reduces friction, prevents fluff, end breakage, and has antistatic properties.
  •  It is not sticky to rubber, plastic, etc., and can be used as a release agent for various rubber and plastic molding processes.
  • Due to the low surface tension of disilicon oil, it can be used as a defoamer in various industries.
  •  Dip-coating silicone oil on motors, electrical appliances and electronic instruments can improve the effect of moisture-proof insulation.
  • It can also be used as additives for other items such as paints, inks, polishing oils, etc.
  • Adding silicone oil to cosmetics can improve the moisturizing and protective effect of the 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.
