Super Low Viscosity Silicone Fluids

Super Low Viscosity Pure Silicone Fluids are clear, colorless, and odorless linear Polydimethylsiloxane fluids / PDMS Silicone Oils that range in viscosities from 0.65cSt (thinner than water) to 2cSt (centistokes) @ 25°C.
They are characterized by their low pour points, volatile nature (evaporate in open system), stability at low temperature, low surface tensions (high spreadability), low viscosity‐to‐temperature coefficients (viscosity changes little even at extremely low temperatures), low MW, low viscosities (all close to water), high dielectric strength and RI values ranging from 1.3750 to 1.3900.

Polydimethylsiloxane Fluid : Guide

Due to their low molecular weight and refractive index values, Low Viscosity Pure Silicone Fluids are widely used in Optics research, LED technologies & Sensor technologies.

Low Viscosity Silicone Fluids are widely used as laboratory bath fluids / heat transfer fluids due to their low viscosity, low pour points, low viscosity change at temperature and high dielectric strength,…
Unlike higher viscosities PDMS Silicone Oils, Super Low Viscosity Silicone Fluids are characterized by their volatility (varying rates of evaporation). Combined with their low surface tensions (high spreadability), and non‐greasy feel, they are used as base fluids, carrying agents and wetting agents in a wide range of personal care products.
