Product Introduction
Designed for extreme conditions, HP-300 achieves unmatched stability through its fully fluorinated formulation: minimal evaporation at high temperatures (0.2% at 200°C/24hr, 1.0% at 1,000hr), oxidation resistance for long-term lubrication, and compatibility with most plastics. The fluorochemical structure provides superior resistance to solvents, strong acids/alkalis, and liquefied natural gas, while ensuring reliability in high-vacuum environments.
Application Scenarios
- Semiconductor Manufacturing: Wafer handling robots, vacuum chamber bearings (SEMI-certified for Class 1 cleanrooms) 6.
- Cryogenic Engineering: LNG valve seals, cryogenic pump bearings (resists -196°C liquid nitrogen)
- Chemical Processing: Agitator shafts in solvent reactors, metering pump gears (withstands strong acids/alkalis)
- Aerospace: Satellite mechanisms, rocket fuel valves (validated for high-vacuum stability)
