Fomblin® S VAC 250 is a new developed grade of PFPE lubricant for vacuum pump. Thanks to its high viscosity index, the film thickness at high temperature improve the lubrication performances of components in vacuum pump systems. An optimum concentration of antirust additive was studied to provide protection against rust and at the same time to guarantee the physical properties and the vacuum performance of the grade.Features: Chemical Resistant; High Density; High Heat Resistance Information provided by Solvay Specialty Polymers. |
