Molykote HP-870 is a high-performance fully fluorinated grease designed for demanding environments that require stable lubrication under extreme temperatures and chemically aggressive conditions. Users experience exceptionally consistent lubrication, clean operation, and long service intervals due to its highly inert formulation. The grease delivers a uniform feel during application, maintains stability in vacuum or corrosive atmospheres, and offers reliable performance where conventional greases fail. It is ideal for precision systems where long-term reliability, minimal contamination, and predictable operation are critical.

• Wide Temperature Tolerance – Molykote HP-870 operates reliably from minus 20 degrees Celsius to 250 degrees Celsius. This wide range is enabled by its fluorinated polymer composition and penetration rating of 280 millimeters per ten strokes, which keeps consistency stable under thermal cycling. The formulation prevents thinning or hardening during heating or cooling, supporting continuous lubrication in extreme processing conditions.

  
  

• Oxidation Resistance – The fluorinated base oil resists oxidative degradation during long-term exposure to air, ozone, or heat. PFPE-based lubricants show exceptionally low decomposition rates in standardized oxidation tests, allowing the grease to maintain structural integrity. This extends service intervals, reduces lubricant failure, and improves reliability in systems requiring sustained performance.

  
  

• Water Resistance – Its hydrophobic fluorinated structure maintains lubricity despite high humidity, wet exposure, or direct water contact. With a density of approximately 2.0 grams per cubic centimeter, the grease maintains strong adhesion to metal surfaces, resisting washout and preserving film strength. This supports dependable operation in moisture-rich industrial settings.

  
  

• Material Compatibility – HP-870 is compatible with plastics, elastomers, and chemically sensitive components due to its inert composition and PTFE thickener. Testing with rubber seals and polymer gears demonstrates minimal swelling and degradation. This ensures safe use in assemblies requiring low reactivity and long-term dimensional stability.

  
  

• Low Volatility – The grease features extremely low evaporation loss, supported by its fluorinated molecular structure. Low volatility prevents mass loss during extended heating or vacuum exposure, maintaining lubrication film thickness. This ensures long-term operational consistency in sealed environments and high-vacuum systems.

• Semiconductor Manufacturing – Used in wafer handling mechanisms, precision motion components, and high-vacuum tools where low volatility and chemical cleanliness are essential. The grease minimizes contamination risk and ensures stable torque behavior during continuous cycles.

  
  

• Cleanroom Equipment – Molykote HP-870 supports actuators, linear guides, and robotic assemblies requiring low outgassing and non-migrating lubrication. Its chemical inertness helps maintain environmental purity and equipment reliability.

  
  

• Cardboard and Paper Processing – Suitable for heated rollers, bearings, and high-speed mechanical contacts exposed to moisture or temperature fluctuations. The grease maintains film strength and reduces wear in continuous production lines.

  
  

• Electronics Assembly – Used in miniature gears, connectors, and thermal-exposed mechanisms where material compatibility and heat stability are required. It protects sensitive components without causing residue or plastic damage.

  
  

• High-Vacuum Systems – Provides dependable lubrication for vacuum pumps, sealing interfaces, and analytical instruments due to extremely low volatility and chemical resistance. It helps maintain chamber purity and reduces system downtime.

  
  

• Chemical Processing – Effective on valves, seals, and bearings exposed to corrosive gases or solvents. The grease maintains structural integrity and lubrication even under aggressive chemical influence, ensuring reliable plant operation.
