Exceptional Stability Under Thermal Stress

Polyvinyl Methyl Siloxane (PVMS) Fluid is engineered for lubrication applications where conventional hydrocarbons and standard PDMS fluids fail. The integration of vinyl groups along the polymer chain significantly enhances its thermal-oxidative stability. While standard methyl silicones may thicken or form silica gel above 150°C, PVMS can operate continuously at 200-250°C and intermittently up to 300°C.

This stability, combined with its low volatility and high film strength, makes it an ideal base fluid for high-temperature greases. When thickened with lithium complex or specialty soaps, PVMS-based greases demonstrate:

Reduced Oxidation: Up to 10x longer service life in high-speed bearing applications compared to mineral oil greases.

Excellent Lubricity for Plastics: Prevents stress cracking in polycarbonate and nylon gears.

Broad-Temperature Performance: Effective from -40°C to 250°C, making it suitable for aerospace mechanisms and industrial oven conveyor chains.
