Description: Low Temperature Silicone Heat Transfer Fluids are clear, colorless, and odorless linear Polydimethylsiloxane fluids / PDMS Silicone Oils that range in viscosities from 1.5cSt to 20cSt (centistokes) @ 25°C. They are characterized by their low viscosities, low pour points, good heat capacity, wide service temperature range, stability at extremely low temperature, low viscosity‐to‐temperature coefficients (viscosity changes little even at extremely low temperatures), hydrophobic nature, high dielectric, strength Newtonian behavior under shear, low weight (lighter than water), stability under high pressure, and RI values ranging from 1.3874 to 1.4000.

PSF‐1.5cSt, PSF‐2cSt and PSF‐5cSt Silicone Heat Transfer Fluids are widely used as heat transfer mediums in freeze drying applications.
