PEEK Plate Applications by Industry

PEEK plates are used where heat resistance, strength, wear performance, and dimensional stability are critical across demanding industrial environments.

SEMICONDUCTOR

PEEK plates suit semiconductor equipment because they combine heat resistance, chemical stability, and precise dimensional control. They are commonly used for wafer handling fixtures, insulating parts, and process components that must remain stable in clean, demanding production environments.

MEDICAL

In medical applications, PEEK plates are valued for repeated sterilization resistance, low moisture absorption, and reliable strength. They are used for trays, housings, instrument parts, and radiolucent support components where cleanliness, stability, and long service life are important.

EV / AUTOMOTIVE

For EV and automotive systems, PEEK plates offer strong electrical insulation, heat resistance, and wear durability. They are suitable for insulating plates, wear parts, and battery-related components that need lightweight performance and long-term reliability under thermal and mechanical stress.

OIL & GAS

PEEK plates perform well in oil and gas service because they resist heat, pressure, wear, and many aggressive chemicals. They are often machined into seals, valve seats, bearing surfaces, and structural parts that must keep working in harsh operating conditions.

INDUSTRIAL MACHINERY

In industrial machinery, PEEK plates are widely used for gears, sliding elements, bearing cages, and compressor valve parts. Their wear resistance, load capacity, and dimensional stability help improve service life and reduce maintenance in high-speed or high-temperature mechanical systems.

FAQs

Find quick answers about PEEK plate grades, dimensions, machining options, temperature performance, and common industrial applications.

In general, PEEK sheet usually refers to thinner flat stock, while PEEK plate is used for thicker sections intended for structural parts, wear components, or machining blanks. In many industrial applications, the two terms may overlap, but plate normally implies greater thickness and heavier-duty use.
Standard PEEK plate thicknesses are available from 4 mm to 120 mm. This range supports thin insulating parts, medium-duty machined components, and thick plates for larger structural or wear-resistant applications.
Bearing grade PEEK is the preferred option for bearing and wear applications. It is typically modified with lubricating fillers such as PTFE, graphite, and carbon fiber to provide lower friction, improved wear resistance, and more stable sliding performance.
Yes. PEEK plate is widely used in semiconductor equipment because it offers high temperature resistance, dimensional stability, low moisture absorption, and strong resistance to many processing chemicals. It is suitable for wafer handling fixtures, insulating parts, and other precision components.
Yes. PEEK plates can be CNC machined into custom parts such as insulators, seals, valve components, bearing parts, structural supports, and other precision-engineered components. Machining can be arranged based on drawings, dimensions, or samples.
PEEK plate has a continuous working temperature of approximately 260°C. This makes it a reliable material for demanding environments where standard engineering plastics may soften, deform, or lose strength.
Yes. PEEK plate offers excellent resistance to many chemicals, moisture, and hydrolysis, which makes it suitable for aggressive industrial environments. For highly specific media or extreme concentrations, material compatibility should still be confirmed before final selection.
Yes. Cut-to-size service and custom dimensions can be provided based on project requirements. This helps improve material utilization, reduce machining waste, and simplify downstream processing for custom components.
PEEK plates are commonly used in semiconductor, medical, EV and automotive, oil and gas, and industrial machinery applications. They are selected where heat resistance, wear performance, strength, insulation, and dimensional stability are critical.
Choose unfilled PEEK for balanced all-round performance and general chemical or electrical parts. Choose GF30 PEEK when you need better dimensional stability and insulation. Choose CF30 PEEK when maximum stiffness, higher load capacity, and stronger mechanical performance are the main priorities.
