What is PEEK?

High-Performance Engineering Thermoplastic

PEEK is a semi-crystalline aromatic polymer known for its exceptional combination of mechanical and chemical properties.

Compared with standard engineering plastics, PEEK maintains its performance under:

1. High temperatures
2. High mechanical loads
3. Aggressive chemicals
4. High-pressure environments
5. Continuous operation conditions

 

These characteristics make PEEK a preferred material for critical sealing applications in semiconductor, energy, chemical processing, and hydraulic systems.

Key Features & Benefits

 

 

Excellent High Temperature Performance

 

PEEK maintains mechanical properties at elevated temperatures and offers continuous operating capability up to approximately 250°C depending on application conditions.

 

Outstanding Mechanical Strength

 

 

PEEK provides superior:

Compression resistance

• Creep resistance
• Wear resistance
• Dimensional stability

 

Excellent Chemical Resistance

 

PEEK demonstrates outstanding resistance against many:

• Hydrocarbons
• Fuels
• Oils
• Solvents
• Chemicals
• Process fluids

 

Low Friction and Wear Resistance

 

 

PEEK materials can be modified with fillers such as:

Carbon fiber

Glass fiber

Graphite

PTFE

to improve:

Wear resistance

Friction performance

Load capability

This makes PEEK suitable for dynamic sealing and guiding applications.

PEEK vs Traditional Engineering Plastics

PEEK provides a balanced combination of properties, making it suitable for extreme applications where standard plastics cannot provide sufficient reliability.

FAQ

 

 

01.What is PEEK material used for in sealing applications?

PEEK is used for high-performance sealing components such as backup rings, wear rings, guide rings, bushings, and precision polymer parts requiring high temperature, chemical resistance, and mechanical strength.

02.Is PEEK better than PTFE for sealing applications?

PEEK offers much higher mechanical strength and load resistance than PTFE, while PTFE provides superior chemical resistance and lower friction. The best material depends on the application requirements.

03.What temperature can PEEK withstand?

PEEK can typically operate continuously at temperatures up to approximately 250°C depending on material grade and application conditions.

04.Can KAFLON manufacture custom PEEK seals?

Yes. KAFLON provides custom PEEK sealing components manufactured according to customer drawings, specifications, and application requirements.

05.How to choose the size of the sprocket?

The standard of sprockets can be determined according to different application requirements. The difference between metric sprockets and sprockets built to ANSI standards is that they use different units of measurement for chain specifications.
