Inferior Lubrication Protection for Critical Pump Components
Highly Reactive or Flammable Lubricating Oils
Krytox™ 1531XP is engineered for premium lubrication & protection for a range of vacuum pump applications where rust & corrosion are problematic.
While Krytox™ VPF fluids are inert and non-reactive to all elastomers, plastics, and metals, the soluble additives in Krytox™ XP products have not been tested with all materials.
Initial testing has shown no problems with Teflon™ fluoroplastic resin, Kalrez® perfluoroelastomer parts, Viton™ fluoroelastomer, nitrile, and silicone rubbers.
The performance of the soluble additives could degrade at temperatures more than 182 °C (360 °F) over a long period of time.
Vacuum pumps are critical in manufacturing processes in a wide range of industries. ChemPoint has partnered with the industry leading VPF manufacturers to maximize pump efficiency and lifespan.
