MOLYKOTE HP-500 is a fully fluorinated grease specifically designed for extreme conditions and precision applications such as cleanroom and semiconductor manufacturing equipment. It is based on a high-purity perfluoropolyether (PFPE) fluid and thickened with polytetrafluoroethylene (PTFE), providing stable lubrication even in environments exposed to strong chemicals, vacuum, or high temperatures. The grease offers outstanding performance with minimal evaporation loss, ensuring long-lasting lubrication without residue or corrosion.

• Compatible With Most Plastics - MOLYKOTE HP-500 is chemically stable and non-reactive with common materials such as PTFE, PEEK, and FKM. After 500 hours of contact at 150°C, no swelling, discoloration, or surface change was observed. This ensures the grease can be safely applied to precision mechanisms containing mixed plastic and metal components without risk of corrosion or material degradation.

  
  

• Excellent Stability at High Temperatures - With a service temperature range of -20°C to 200°C and temperature resistance up to 204°C, HP-500 retains its viscosity and lubricating ability even during continuous high-temperature exposure. Thermal stability tests showed less than 1% mass loss after 24 hours at 200°C.

  
  

• Superior Resistance to Chemicals and Solvents - The PFPE-based formulation provides outstanding resistance to acids, alkalis, and organic solvents. When exposed to hydrochloric acid vapor and solvent mixtures for 72 hours, HP-500 maintained full structural integrity and showed no decomposition. 

  
  

• Minimal Deterioration Due to Oxidation; Appropriate for Long-Term Lubrication - HP-500 resists oxidative breakdown in oxygen-rich or reactive environments. In long-term tests at 150°C for 1000 hours, viscosity change remained within ±5%, ensuring continuous lubrication without sludge formation or hardening. 

  
  

• Low Vapor Pressure (Base Oil) - The product’s PFPE base oil exhibits an extremely low vapor pressure, measured at 1×10^-8 Torr at 20°C. This prevents outgassing and particle generation in vacuum systems or cleanrooms, ensuring stable performance and maintaining the cleanliness required in sensitive applications such as semiconductor manufacturing or optical instruments.

• Semiconductor - MOLYKOTE HP-500 is used in wafer handling robots, vacuum pumps, and cleanroom systems to prevent contamination while ensuring smooth mechanical movement. Its low vapor pressure minimizes outgassing, maintaining the integrity of semiconductor production environments.

  
  

• Electronics - The grease provides reliable lubrication for precision electronic components, switches, and connectors. Its dielectric strength of >450 V/mil ensures insulation between metal contacts, reducing the risk of electrical discharge or current leakage.

  
  

• Chemical Processing - HP-500 withstands exposure to strong acids, bases, and organic solvents, ensuring consistent lubrication in chemical pumps, valves, and mechanical seals. It prevents wear and chemical attack during continuous operation in corrosive atmospheres.

  
  

• Pharmaceutical - The non-reactive and clean characteristics of HP-500 make it suitable for pharmaceutical manufacturing machines, where it maintains lubricity even after sterilization or exposure to cleaning agents, ensuring hygiene and operational stability.

  
  

• Automotive - In automotive applications, HP-500 is used in oxygen sensor threads, fuel system parts, and high-temperature motor bearings. It remains stable under 204°C, preventing carbonization and ensuring consistent lubrication over long periods.

  
  

• Aerospace - MOLYKOTE HP-500 provides durable lubrication for actuators, connectors, and bearing systems exposed to vacuum and temperature extremes. It maintains mechanical reliability from -57°C to 204°C, making it suitable for both spacecraft and high-altitude aviation systems.
