As a China-based PEEK material manufacturer, The PEEK board of PRES is produced by continuous extrusion molding, which enables consistent thickness and width of the board, and allows for more flexible control of the PEEK sheet's length, ranging from 1000mm to 3000mm.Moreover, the production speed of extrusion is faster than compression molding. The surface flatness and smoothness are also better, making it more suitable for the production of large-scale orders.
polyetheretherketone (PEEK) sheet from PRES supply in five grades — unfilled, GF30, CF30,Bearing grade and ESD grade.Standard size is 620×1240 mm, with grade-dependent thickness from 1 to 150 mm.
Why PRES PEEK Sheets?
The plates of PRES undergo annealing treatment after production to enhance the crystallinity of the material, thereby achieving better rigidity, better chemical corrosion resistance and higher flatness of the PEEK plates. And after annealing, the internal stress of the plate is even lower, reducing the risk of warping during storage and transportation. Moreover, it can also minimize the deformation and cracking risks of PEEK products during processing.
The PRES system offers very flexible ordering quantities for sheet materials in stock. You can make purchases based on the actual needs of the project or conduct small-scale sample tests. And we can customize the color for you (for un-filled PEEK and PEEK GF30 sheets)

Typical commercial specifications. Mechanical and thermal figures — HDT, continuous service temperature, thermal conductivity, water absorption — are kept on the dedicated thermal performance page and in the selection guide to avoid duplication. Made-to-order blanks beyond stock thickness are available on request; lot-specific certified reports available upon request.
Leveraging the inherent flatness and dimensional stability of annealed PEEK sheets, PRES stock shapes are routinely machined into:
Wear Plates and Sliding Bases — Utilizing ≥98% flatness for linear motion systems in semiconductor equipment.
Seal Backing Plates and Gaskets — Chemical resistance + tight thickness tolerance (±0.20 mm) for fluid handling.
Structural Brackets and Insulating Plates — High flexural modulus (4.1–23 GPa) for aerospace secondary structures.
Precision Fixtures and Jigs — Annealed stability (±0.05 mm/m) ensures repeatable CNC fixture accuracy.
Q: What is the standard stock size and thickness of PRES PEEK sheets?
A: Standard panels are 620×1240 mm. Stock thickness: unfilled 1–150 mm, GF30/CF30 6–150 mm, ESD 6–150 mm. Thicker made-to-order blanks (unfilled up to 170 mm) are available on request.
Q: What is polyetheretherketone (PEEK) sheet used for?
A: Polyetheretherketone is a semi-crystalline high-temperature thermoplastic (melting point 343°C, glass transition 143°C, continuous service 260°C). In sheet form it is machined into wear plates, seal backing rings, insulating panels and precision fixtures — see the full introduction on our What is PEEK material page.
Q: Which grade is FDA-compliant for medical and food equipment?
A: Unfilled natural beige PEEK sheet, 1.30 g/cm3, compliant with 21 CFR 177.2415.
Q: What is the price of PEEK sheet? Is there a minimum order?
A: Pricing depends on grade, thickness and quantity. Small trial orders and stock cuts are welcome — see indicative figures in our PEEK price guide or request a quote with your sizes.
Q: Do you offer cut-to-size service and what tolerance can you hold?
A: Yes. Panels are CNC cut to your finished sizes with thickness tolerance as tight as ±0.20 mm; lead time depends on size and quantity — send your drawing for a schedule.
Q: Why are PRES PEEK sheets annealed at 250°C?
A: Stress-relief annealing at 250°C ±5°C with slow cooling (≤10°C/hr) removes the residual stress locked in during extrusion. Without it, machining releases that stress as warpage. Thicker panels go through extended or multi-cycle annealing.
