Wacker Wacker® AK 500000 Silicone Fluid
Categories:	Fluid; Polymer; Thermoset; Silicone
Material Notes:	Product description: WACKER® AK 500 000 is a linear, non-reactive polydimethylsiloxane with a viscosity of approx. 500 000 mm²/s. Due to its chemical structure, WACKER® AK 500 000 has an outstanding property profile, which sets it apart from organic materials such as mineral oils. Properties: WACKER® AK 500 000 is a clear, odorless and colorless liquid. Special features: minimal change in physical properties over a broad temperature range excellent water-repellent properties good dielectric properties low surface tension and thus high surface activity chemically highly unreactive low solidifying point high flash point high heat resistance good solubility in a wide range of solvents Application: antifoam agent liquid dielectric for electrical and electronic equipment plastics additive damping medium Silicone fluids from the BELSIL® line are available for the cosmetic sector. Whenever particularly high heat and shear resistance is required, manufacturer recommends silicone fluids from the AK stab, AK visc and AKC product lines. Information provided by Wacker Chemie AG.
