Wacker WACKER AK 500000 SILICONE FLUID is a high-viscosity linear non-reactive polydimethylsiloxane in WACKER® AK series, designed for high-end industrial lubrication, dielectrics and special additives. With ultra-high viscosity stability, excellent temperature and radiation resistance, its performance is superior to organic materials such as mineral oil.
High Viscosity Stability - Viscosity up to 500000 mPa.s, good stability, no obvious attenuation after long-term use
Excellent Temperature & Radiation Resistance - Stable work at -40℃ to 300℃, resistant to electromagnetic, ultraviolet and various particle radiation
Superior Non-Reactivity - Stable chemical properties, no reaction with system components, ensuring formula consistency
Low Volatility & Shear Resistance - Extremely low volatility, outstanding shear stability, no easy loss, longer service life
Outstanding Hydrophobicity & Insulation - Low surface tension, good hydrophobicity, and excellent electrical insulation performance
Industrial Lubrication - Lubrication for precision heavy-duty components, suitable for high-load scenarios, reducing friction and wear
Dielectric Application - Liquid dielectric for electrical and electronic equipment, ensuring insulation stability in high-voltage environments
Hydraulic Oil & Damping - Hydraulic oil and damping fluid for high-end equipment, providing stable hydraulic and damping effects
Mold Release Additive - Mold release for high-viscosity products, improving isolation effect and ensuring product surface integrity
Waterproof Protection - Hydrophobic treatment for glass, mineral wool and other substrates, enhancing long-term waterproof and moisture-proof performance
