Dimethicone 1000

A high quality of silicone oil which is clear, water- white, tasteless, odourless and neutral liquid. Its viscosity shows very little change with temperature variation. It exhibits minimum of change among all types of silicone fluids. Outstanding resistance to high and low temperature extremes, maintenance of flexibility over a wide temperature range are its unique properties.

It shows high resistance to breakdown by mechanical shearing. The low change in viscosity with temperature and excellent heat and cold resistance makes it an ideal lubricant. It is, therefore, widely used in gear wheels, bearings and brushes. It exhibits excellent dielectric properties, which are maintained for prolonged periods of time even under varying operating conditions.
