Silicone Fluids
PST-800 Series, DC® 200 and Xiameter® PMX-200 offsets
Silicone Fluids from PolySi® G-MAN® Lubricants 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, provides many alternatives to solve your lubricating needs. Silicone fluids can be formulated into greases or pastes, depending on your application. The fluids include dimethylpolysiloxane, methyl phenyl 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.
