MOLYKOTE® HP-300 Grease
Fully fluorinated grease providing extraordinary performance under extreme conditions. Formulated with perfluoropolyether (PFPE) base oil and fluorinated polymer (PTFE) thickener, it delivers reliable lubrication across a wide temperature range (-65°C to +250°C), in the presence of aggressive chemicals, solvents and high vacuum.
Features and benefits
- Compatible with most plastics and elastomers
- Excellent stability at high temperatures (up to +250°C continuous service)
- Superior resistance to chemicals and solvents
- Minimal deterioration due to oxidation, ideal for long-term lubrication
- Low base oil vapor pressure (2.9×10-7 Pa at 20°C)
- Excellent dielectric properties (dielectric strength: 296 V/mil)
- Waterproof (seal test passed)
- Approved for hydrogen applications and oxygen environments (BAM)
