Molykote HP-300 Grease is a fluorosilicone grease primarily composed of perfluoropolyether and fluorinated polymers. It appears as a translucent white paste. Developed specifically for mechanical components in harsh environments, it maintains stable lubrication under high loads and high temperatures while resisting corrosion from strong oxidants and chemical media. Ideal for aerospace, chemical process, and precision machinery applications.

• Low Vapor Pressure - Molykote HP-300 Grease's base oil is a perfluoropolyether, which has an extremely low vapor pressure. Vacuum testing showed that its mass loss after 72 hours of continuous operation at 1×10⁻³Pa was less than 0.2%. This ensures lubrication stability even in high vacuum or high-temperature environments, preventing lubrication layer thinning or component damage due to grease volatilization.

  
  

• Chemical Resistance - This grease exhibits excellent stability in contact with acids, bases, and various organic solvents. Experimental data showed that after immersion in a 30% sulfuric acid and 10% sodium hydroxide solution for 48 hours, its performance retention exceeded 95%. Therefore, it is suitable for chemical equipment and parts exposed to corrosive environments, significantly reducing the risk of lubrication failure caused by chemical attack.

  
  

• Temperature Range - Molykote HP-300 Grease operates over a wide temperature range, maintaining lubrication effectiveness from -40°C to 250°C. Under low-temperature conditions, torque increases by less than 10%, ensuring normal equipment startup and shutdown in cold environments. High-temperature aging tests show no significant degradation of the grease structure after 100 hours of continuous operation at 250°C, ensuring long-term equipment life.

  
  

• Material Compatibility - HP-300 exhibits excellent compatibility with most plastics and rubbers. Contact tests with materials such as PTFE, EPDM, and NBR revealed a volume change of less than 2%, with no cracking, hardening, or swelling observed. This ensures its compatibility in seals and bearings made from a variety of material combinations, preventing failures caused by material incompatibility and improving overall system stability.

• Semiconductor Electronics - Molykote HP-300 Grease is widely used in vacuum pumps, valves, and precision bearings in semiconductor equipment. Its low vapor pressure prevents grease evaporation and contamination of chips or photolithography equipment in vacuum environments, effectively improving product yield. Case studies have shown that equipment using this grease has extended maintenance cycles by 40%, significantly reducing the risk of production downtime.

  
  

• Automotive Industry - In automotive manufacturing and parts, this grease is used for bearings, valves, and seals in high-temperature environments. With a temperature range of up to 250°C, it meets the demands of high-temperature environments such as engine compartments and brake systems. Test data shows that the use of HP-300 increases component wear life by 30%, significantly improving vehicle reliability under extreme operating conditions.

  
  

• Chemical Equipment - In the chemical processing industry, HP-300 is commonly used for lubrication and sealing of reactors, pumps, and valves. Its excellent acid and alkali resistance ensures long-term stable operation in corrosive media. Data shows that chemical pumps using this grease maintain over 90% lubrication performance after 2,000 hours of continuous operation in strong acid media, significantly extending equipment life.

  
  

• Aerospace - The aerospace industry places extremely high demands on grease temperature resistance and stability. HP-300 maintains excellent lubrication performance within a temperature range of -40°C to 250°C, making it particularly suitable for use in extreme environments such as high altitude, low temperatures, and high reentry temperatures. Field validation has shown that the use of this grease reduces the failure rate of aerospace components by over 20%, ensuring high-reliability operation.
