Silicone Greases

Greases and Oil compounds

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 oil 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 oil compounds are used primarily in electrical insulators
and seals, and for heat dissipation and water repellency.

Features

	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.
	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.

	Safety
	The silicone fluid base oil is chemically inactive, so these products pose almost no risk to humans and animals.
	Efficiency
	Excellent performance even when used in small amounts.
