Overview
Krytox™ 1531XP is a highly engineered PFPE-based oil for use in vacuum pump systems where traditional lubricants cause safety, waste disposal, or maintenance concerns. Krytox™ 1531XP delivers exceptional performance with completely nonflammable and nonreactive chemistry for chemical and oxygen service applications.
Krytox™ 1531XP Oil has a viscosity of 63 cSt at 50°C and is distilled for an extremely high-temperature operating range. Krytox™ 1531XP has been formulated with oil-soluble additives to prevent and protect equipment from rust and corrosion.
Features & Benefits
- Nonflammable
- Nonreactive/Inert chemistry
- Recyclable
- Oxygen safe
- Robust thermal stability
- High-quality vacuum pump fluid
Problems Solved
Corrosion and rust formation on pump and vacuum system
Inferior hydrocarbon lubricant protection for critical pump components
Highly reactive or flammable lubricating oils or VPF oils
Applications
Krytox™ Krytox™ VPF fluids are inert and nonreactive 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 over a long period at temperatures more than 182°C (360°F).
