Description
Name: Polydimethylsiloxane Fluid
CAS NO.:63148-62-9
Structural formula:
VES-201C is a linear, non-reactive polydimethylsiloxane in a wide range of average kinematic viscosities. Due to the non-reactive structure and non-polar group, it has excellent water-repellent properties, good dielectric properties, high damping action.
Key Features
• Anti-Oxidation, Chemical and weather resistant.
• Excellent Water-Repellent.
• High dielectric strength
• High damping action.
• Low surface tension.
