High Viscosity Pure Silicone Fluids for use in Flow Control, Temperature Control, Pressure Control, Motion Control, and Vibration Control Instruments, Gauges & Sensors

Description: High Viscosity Pure Silicone Fluids are clear, colorless, and odorless linear Polydimethylsiloxane fluids / PDMS Silicone Oils that range in viscosities from 5,000cSt to 100,000cSt (centistokes) @ 25°C. They are characterized by their thick viscosities, high damping action, high flash points, wide service temperature range, low viscosity change at temperature (low VTC), excellent lubricity, stability under high pressure, high dielectric strength, RI Values between 1.3970 to 1.4000, and inertness to virtually all substrates.

Chemical Name: Polydimethylsiloxane Fluid / PDMS Silicone Oil

CAS No: 63148-62-9

High Viscosity Silicone Fluids are used in a wide range of instruments, gauges, sensors and meters to monitor and control temperature, pressure, vibration motion & humidity. Their thermal properties and high damping action help to ensure the most accurate reading and images in gauges/instruments/meters and sensors, under the most adverse conditions.
