SILICONE OIL 50 cPs/cSt
Xiameter Pmx-200 Silicone Fluid 50cs
Dimethicone 50
Cosmetic / Industrial / Laboratory
A high quality of silicone oil which is clear, water- white, tasteless, odorless 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.
It is soluble in many solvents and can be used as an active ingredient in cosmetic, automotive, furniture, metal and speciality polishes providing lubrication, softness and silky feel.

Common Uses of Silicone 50 (50 cSt PDMS)
1. Lubricant and Release Agent
-
Plastic, rubber, and metal mold release
-
Food-grade lubricants (if FDA-compliant)
-
Lubrication for rubber gaskets, seals, and O-rings
2. Polishes and Surface Protectants
-
Used in automotive polishes, furniture sprays, and vinyl protectants
-
Adds gloss and water repellency to surfaces like plastics, dashboards, and metals
3. Antifoam & Defoamer Base
-
May be used as-is or modified into antifoam emulsions
-
Effective in industrial cleaning, wastewater, and fermentation systems
4. Cosmetic & Personal Care
-
Used as a non-greasy emollient in:
-
Hair serums
-
Skin creams
-
Shaving products
-
-
Gives a smooth, silky feel and enhances spreadability
Silicone 50 is to be used as a surface agent or for de-soaping creams and lotions. However, 1–10% is needed for applications such as hand creams and lotions to form a more uniform film and effective barrier.
5. Dielectric & Thermal Stability
-
Used in electronic lubricants, insulating fluids, and coolants
-
Excellent dielectric properties and temperature resistance
6. Textile & Leather Applications
-
Acts as a softener or hydrophobising agent
-
Used in coating or finishing treatments
