​WACKER AK 5000 Silicone Oil

WACKER AK 5000 SILICONE FLUID is a medium-low viscosity linear non-reactive polydimethylsiloxane in WACKER® AK series, designed for industrial lubrication, diffusion pump oil and textile finishing. With high bond energy Si-O structure, it has excellent temperature resistance, low volatility and strong hydrophobicity, excellent fluidity and processability, outperforming mineral oils.

Features Of WACKER AK 5000 Silicone Oil

  1. Medium-Low Viscosity & Easy Operation - Moderate-low viscosity, excellent fluidity, easy to add and coat, suitable for fine processes

  2. Reliable Chemical Stability - Non-reactive, resistant to acid, alkali and oxidation, good compatibility with most substrates and organic solvents

  3. Wide Temperature Resistance Range - Stable at -55℃ to 300℃, resistant to radiation and high-temperature oxidation, not easy to degrade

  4. Low Volatility & Low Loss - Extremely low volatility, good shear stability, less loss and long service life during long-term use

  5. Outstanding Surface Activity - Low surface tension, excellent hydrophobicity, with good lubrication and dispersion properties

Typical Applications Of WACKER AK 5000 Silicone Oil

  1. Industrial Lubrication - Lubrication for precision instruments and small bearings, reducing friction loss and ensuring stable equipment operation

  2. Diffusion Pump Oil - Special oil for vacuum diffusion pumps, suitable for vacuum environment and ensuring efficient pump operation

  3. Textile Finishing - Waterproof and smoothing finishing agent for textile fibers, improving fabric hand feel and waterproof performance

  4. Mold Release Additive - Mold release for light rubber and plastic products, easy to peel off, no impact on product surface finish

  5. Dielectric Application - Insulation for low-voltage electrical equipment, suitable for high-low temperature environments with stable insulation
