Silicone Transformer Oil is a 100% Polydimethylsiloxane silicone oil (CAS# 63148-62-9) with a viscosity of 50cSt (centistoke) @ 25°C. STO-50 Silicone Transformer Oil is formulated exclusively for use as a dielectric fluid and dielectric coolant in high voltage transformers transformers.

If you require a silicone fluid for use in a transformer, silicone transformer oil is a clear, colorless and odorless linear Polydimethylsiloxane fluid (CAS# 63148-62-9) with a viscosity of 50cSt. Unlike conventional fluids, silicone transformer oil is dehydrated to contain < 50ppm water content to ensure the highest degree of dielectric strength and thermal stability. It meets IEC 836 specifications for use in a transformer.

Low Temperature Dielectric Silicone Fluids (-80°C to 220°C) are clear, colorless and odorless linear Polydimethylsiloxane fluids that are characterized by their high dielectric strength, low viscosity, low viscosity-to-temperature coefficients (little viscosity change at low temperatures), low pour points, stability @ low temperatures, and compatibility with virtually all surfaces including metal, rubbers and plastics. The PSF-2cSt and PSF-5cSt are widely used in Freeze Drying and heat transfer applications that require a fluid with low viscosity and low pour point.

Wide Temperature Dielectric Silicone Fluids (-50°C to 230°C) are clear, colorless and odorless linear Polydimethylsiloxane fluids (CAS# 63148-62-9). They are characterized by their dielectric strength, high flash points, high thermal stability, high resistance to oxidation, low vapor pressure, and compatibility with virtually all surfaces including metal, rubbers and plastics.

High Temperature Dielectric Silicone Fluids (25°C to 300°C) are clear, colorless and odorless phenyl-class silicone fluids. They are characterized by their high dielectric strength, high flash points, high thermal stability, high resistance to oxidation, low vapor pressure and compatibility with virtually all surfaces including metal, rubbers and plastics.
