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. They are particularly effective for baths and systems that have to circulate. Unlike higher viscosity fluids, their viscosities remain low even at extremely low temps. As such, they are easy to circulate and pump.
The low molecular weight and refractive index values of Low Viscosity Pure Silicone Fluids make them widely used in Optics research, LED technologies & Sensor technologies.
