PEEK Plastic Plate – Properties, Applications & Buying Guide

What Is PEEK Plate?

PEEK plate is a high-performance engineering plastic sheet manufactured from Polyether Ether Ketone (PEEK), one of the most advanced thermoplastic polymers available today. Known for its exceptional heat resistance, mechanical strength, and chemical stability, PEEK plate is widely used in demanding industries such as aerospace, semiconductor, medical, oil & gas, and precision engineering.

Compared to standard engineering plastics, PEEK plate offers:

• Continuous service temperature up to 260°C (500°F)

• Excellent wear and friction performance

• High dimensional stability

• Outstanding chemical resistance

• Superior mechanical strength

PEEK plate is typically produced through compression molding or extrusion and supplied in various thicknesses for machining applications.

PEEK Plate vs Other Engineering Plastics

PEEK plate is selected when long-term mechanical strength at high temperatures is required.

Machining PEEK Plate

PEEK plate is highly suitable for CNC machining. Due to its mechanical stability and predictable cutting behavior, it can be processed into:

• Precision gears

• Seal rings

• Valve components

• Structural frames

• Insulation parts

For thick plates, stress-relief annealing before machining is recommended to ensure dimensional stability.

Our custom machining services include:

• CNC milling

• CNC turning

• Drilling & tapping

• Tight tolerance finishing

How to Choose the Right PEEK Plate

When selecting PEEK plate, consider:

1. Operating temperature

2. Mechanical load requirements

3. Wear resistance needs

4. Chemical exposure

5. Dimensional stability requirements

6. Regulatory requirements (FDA, medical grade)

If stiffness and strength are critical → choose CF30 PEEK plate
If chemical resistance and purity are critical → choose natural PEEK
If wear resistance is key → choose modified PEEK
