Silicone Fluids by PolySi Technologies:
PST-800 Series, DC® 200 and Xiameter® PMX-200 offsets

Silicone fluids by PolySi Technologies perform under the most extreme industrial conditions and over a wide range of temperatures. Silicone fluids resist salts, dilute alkalis and acids, and resist harsh chemicals, fuels and solvents. They also resist evaporation, oxidation, and radiation; they are non-carbonizing, and inherently inert. The range of silicone fluid viscosities, from 1cst- 600,000 cst, provide many alternatives to solve your lubricating needs. They can be formulated into greases or pastes, depending on your application. The fluids include dimethylpolysiloxane, methylphenyl fluids, and alkyl blends. These materials are commonly used to lubricate o-rings extending the life and reducing the wear, mold releases, release agents, diluent fluids, dampening media and rubber components.
