MOLYKOTE HP-300 Grease: PFPE Lubrication for Extreme Conditions

When machinery operates under extreme temperatures, aggressive chemicals, solvents, high vacuum, or other demanding conditions, selecting the right lubricant is essential for maintaining reliable equipment performance. MOLYKOTE HP-300 Grease is designed for applications where long-term lubrication and resistance to environmental degradation are important.

Based on perfluoropolyether (PFPE) technology and thickened with PTFE, MOLYKOTE HP-300 provides a stable lubrication film for components exposed to challenging operating environments. The grease is classified as NLGI Grade 2 and has a service temperature range of approximately -65°C to 250°C, making it suitable for both low-temperature and elevated-temperature applications.

Key Performance Characteristics

One of the main advantages of MOLYKOTE HP-300 is its resistance to chemicals and solvents. This makes it a practical choice for equipment where conventional hydrocarbon-based lubricants may deteriorate or become unsuitable.

The grease also features low base-oil vapor pressure, which is particularly useful in applications where excessive lubricant volatilization needs to be minimized. This characteristic makes HP-300 relevant to cleanroom and semiconductor manufacturing environments.

Other notable characteristics include:

• PFPE-based synthetic grease for severe operating environments
• NLGI Grade 2 consistency
• Service temperature range from approximately -65°C to 250°C
• Excellent resistance to chemicals and solvents
• Good compatibility with many plastics and rubber materials
• Low volatility and low vapor pressure
• Good resistance to oxidation and long-term lubricant deterioration
• Suitable for corrosive and reactive environments
• White grease appearance for applications where clean lubrication is preferred

Typical Applications

MOLYKOTE HP-300 can be considered for a wide range of specialized lubrication requirements, including:

• Rolling-element bearings
• Valves, seals, O-rings and packings
• Plastic components and sliding parts
• Rubber and elastomer components
• Cleanroom machinery
• Semiconductor manufacturing equipment
• Equipment exposed to solvents or aggressive chemicals
• High-vacuum applications
• Components operating at low or high temperatures
• Electrical and specialized industrial equipment

For applications requiring dependable lubrication in chemically aggressive or low-volatility environments, HP-300 offers a PFPE-based alternative to conventional industrial greases. Its combination of broad temperature capability, chemical resistance and material compatibility makes it particularly suitable for specialized machinery and precision equipment.
