WACKER® AK 500 is a linear, non-reactive polydimethylsiloxane with a viscosity of approximately 500 mm²/s. Its chemical structure imparts exceptional properties that distinguish it from organic materials like mineral oils. WACKER® AK 500 exhibits excellent dielectric properties, low surface tension resulting in high surface activity, and a high degree of chemical inertness. These characteristics make it well-suited for various applications where these specific properties are required.

Processing

  • Due to WACKER® AK 500 many diverse applications, no general processing information can be provided. Parameters will vary from application to application.
  • Available in a range of viscosities, WACKER® SILICONE FLUIDS AK are miscible with each other in any ratio.
  • The standard product's viscosity can thus be altered to suit your individual needs.
  • WACKER® AK 500 is a non-polar liquid and is immiscible with polar solvents such as water or short-chain alcohols. In aliphatic and aromatic hydrocarbons, chlorohydrocarbons, ethers, esters, ketones and higher alcohols, WACKER® AK 500 is soluble in any proportion.
