Product Overview

Dimethyl Silicone Oil 10cst CAS 63148-62-9 is low-viscosity linear polydimethylsiloxane (PDMS).

Manufactured under precise polymerization process with strictly controlled viscosity. The product has excellent dielectric strength, reliable heat transfer efficiency, low volatility and stable physicochemical characteristics. It is chemically inert to most plastics, metal parts and encapsulation materials used in electronics. While transferring heat away from working devices, it provides continuous electrical insulation to prevent short circuits. It is a high-performance dielectric coolant specially designed for electronic and electrical components.
