Silicone greases start with a base oil of silicone fluid, to which are added various additives and fillers (metal soap, etc.). Silicone greases exhibit thermal oxidation stability over a wide temperature range, offer good moisture-resistance, and are used primarily for lubrication. Silicone fluid compounds are products with a grease-like consistency. They are produced by blending materials such as silica powder into a base oil of silicone fluid. They exhibit thermal oxidation stability over a wide temperature range and have outstanding electrical properties and water repellency. Silicone fluid compounds are used primarily in electrical insulators and seals, and for heat dissipation and water repellency.


  • Heat and cold resistance
  • Because the silicone fluid base oil has good resistance to heat and cold, the drop point is high, there is little oil separation, and volatile matter content is low.

  • Safety
  • The silicone fluid base oil is chemically inactive, so these products pose almost no risk to humans and animals.

  • Moisture resistance
  • These products have good resistance to water and moisture. Silicone greases can be left underwater for long periods; the surface will turn white, but there is almost no internal change.

  • Efficiency
  • Excellent performance even when used in small amounts.
