What is Silicon Oil ?

Mr. VS Dave.
I dont think Silicone Oil is the absolutely correct definition (as far as I understand), but Silicone Fluid. Some of the Silicone Fluids are based on Polydimethylsiloxane, some of Alkylaryl Siloxane fluid (According to Dow Corning). I do not know much about theese products, except they are expensive (we have some customers using it as insulating oil in transformers).

If anyone out there has more information I would be very interessed.

"Silicone fluids are typically clear, transparent liquids. Product types range from free flowing, water-like fluids to viscous, syrup-like fluids.

These silicone fluids are resistant to high and low temperatures, water, and chemicals. They have excellent electrical properties, and they exhibit mold releasability, water repellency, and defoaming characteristics not found in ordinary mineral and synthetic oil products.

Silicone fluids are thus used in a variety of applications ranging from electronics, transport machinery, chemicals, machinery, textiles, pulp, construction, civil engineering, cosmetics, and household goods."

Silicone fluid is also used as brake fluid.

Silicone Fluids are based on Polydimethylsiloxane, some of Alkylaryl Siloxane fluid .
THEY ARE SOFTENERS OF VARIOUS INDUSTRIES. THEY ARE HEAT RESISTANT IN TYRES.ETC

Used in some DOT5 brake fluids and used as antiform agents in lube oils.
