What Is PFPE Grease?
PFPE grease is a high-performance lubricating grease made from perfluoropolyether base oil, usually thickened with PTFE. PFPE grease is selected for applications where conventional mineral oil, PAO, silicone or lithium greases may fail due to high temperature, oxygen exposure, aggressive chemicals, vacuum conditions or material compatibility requirements.
Engineering Note
PFPE grease is not chosen only because it is “premium.” It is chosen when the application requires chemical inertness, temperature stability, vacuum performance or oxygen compatibility that conventional greases cannot provide.
Chemically Inert
Resists many aggressive chemicals, solvents, fuels, acids and oxidizing environments.
Non-Flammable
Widely used in oxygen, reactive gas and high-temperature environments where flammability risk must be controlled.
Low Vapor Pressure
Suitable for selected vacuum and semiconductor equipment because of its low volatility and low outgassing behavior.
Material Compatibility
Generally selected for applications involving metals, plastics, elastomers, O-rings and seals.
Do You Really Need PFPE Grease?
Review the conditions below. If your equipment operates under these constraints, PFPE chemistry may be the required lubrication path.
High Temperature
Why PFPE Helps: Can be selected where oxidation, oil evaporation, carbon deposits or hardening shorten the service life of conventional grease.
Vacuum or Low Outgassing
Why PFPE Helps: Low vapor pressure helps reduce contamination risk in selected vacuum equipment and precision assemblies.
Oxygen or Reactive Gas
Why PFPE Helps: Selected for oxygen or reactive gas service where non-flammability and chemical inertness are required.
Aggressive Chemicals
Why PFPE Helps: Resists many solvents, fuels, acids, alkalis and chemical vapors where hydrocarbon greases may dissolve or degrade.
Plastic / Rubber / O-Ring
Why PFPE Helps: Often selected for O-rings, seals and mixed material assemblies where swelling, embrittlement or compatibility risk must be reduced.
Sealed-for-Life Parts
Why PFPE Helps: Can reduce maintenance frequency in applications where relubrication is difficult, expensive or not allowed.

PFPE Base Oil Types: K / Y / M / Z
Not all PFPE greases perform the same. PFPE base oil structure affects low-temperature torque, volatility, viscosity index, load performance, cost and application fit. Morelic can help match K/Y, M or Z type PFPE chemistry according to real working conditions.
Selection Rule
- Heavy load / slow speed → consider K or Y type.
- High speed / precision / vacuum → consider M type.
- Cryogenic / low torque / premium vacuum → consider Z type.
| PFPE Type | Structure | Typical Temperature Fit | Best Application Fit | Buyer Note |
|---|---|---|---|---|
| K / Y Type PFPE | Pendent Structure | Good high-temperature and load performance | Heavy-load, slow-speed, general high-temp components | Cost-effective option for many industrial projects |
| M Type PFPE | Linear Structure | Wide temperature range and low volatility | Vacuum, precision bearings, wide-temperature | Good balance between low volatility and wide-temp |
| Z Type PFPE | Linear Structure | Excellent low-temperature and low-torque behavior | Cryogenic, precision, low-torque and premium vacuum | Premium option when low-temp start-up is critical |
Typical PFPE Grease Parameters
The table below is for initial product selection. Final values should be confirmed by the TDS and sample testing.
| Parameter | Typical Options | Selection Note |
|---|---|---|
| Base Oil | PFPE K/Y, M, Z Type | Determines temperature range, volatility, torque, cost and application fit. |
| Thickener | PTFE | Provides grease structure and helps keep PFPE oil at the friction contact point. |
| NLGI Grade | 0, 1, 1.5, 2 or customized | Affects pumpability, sealing, staying power and application method. |
| Temperature Range | Typical: -40°C to +250°C; special options down to -75°C / -90°C or peaks to +300°C | Needed for high-temperature bearings, cryogenic parts and vacuum equipment. |
| Base Oil Viscosity | Custom viscosity options available | Selected according to speed, load, torque, temperature and dispensing method. |
| Evaporation Loss | Low-volatility and low-evaporation options | Important for high temperature, vacuum and clean equipment. |
| Material Compatibility | Metals, plastics, elastomers and O-rings after testing | Final compatibility testing is recommended using the actual component material. |

| Comparison Item | PFPE Grease | Silicone Grease | PTFE Grease (General) | Lithium / Synthetic |
|---|---|---|---|---|
| Base Chemistry | PFPE oil + PTFE thickener | Silicone oil + thickener | Varies; often PTFE additive | Mineral/PAO + soap complex |
| Best For | Extreme temp, oxygen, vacuum, chemicals & precision | Rubber/plastic lubing, sealing, water resistance | Low-friction sliding, plastic & metal parts | General industrial bearings & machinery |
| High Temp Stability | Excellent, depending on formula | Good, but below PFPE in extreme service | Depends on base oil | Limited under extreme heat |
| Vacuum / Outgassing | Strong option | Limited | Depends on formula | Usually not suitable |
| Oxygen Compatibility | Available for suitable formulas after review | Not generally preferred | Depends on formula | Usually not suitable |
| Chemical Resistance | Very strong | Moderate | Depends on base oil | Limited |
| When to Choose | Use when failure cost, downtime or exposure justifies PFPE | Use for rubber/plastic sealing and water resistance | Use for low-friction without extreme chemical needs | Use for normal industrial lubrication |

Before Using PFPE Grease: Important Notes
PFPE chemistry requires proper handling and application review to ensure performance and cost-effectiveness.
Do Not Mix with Unknown Grease
PFPE grease should not be mixed with mineral, PAO, lithium, silicone or unknown old grease. Clean the lubrication point before conversion.
Use When Justified
PFPE grease has a higher material cost. It is best used where high temperature, oxygen, vacuum, chemical exposure or long-life lubrication justifies the cost.
Check Material Compatibility
PFPE grease is widely selected for plastics and elastomers, but compatibility should still be tested with the actual material.
Confirm Oxygen Service Carefully
Oxygen-compatible PFPE grease should be selected based on pressure, concentration, materials and system requirements.
Avoid Overheating Beyond TDS
PFPE grease is thermally stable, but the final temperature limit must follow the selected product TDS.
Use Proper Cleaning Method
PFPE grease is chemically resistant and may require suitable cleaning methods or fluorinated solvents depending on the application.
