PEEK Plates and Sheets
PEEK (Polyetheretherketone) plates and sheets are semi-finished profiles manufactured from high-performance PEEK thermoplastic resin via extrusion or compression molding. These forms offer flat stock material in defined thicknesses, providing a base for subsequent precision machining (e.g., milling, turning, drilling) to create diverse high-performance engineering components.
The material exhibits exceptional high-temperature resistance, excellent mechanical strength and stiffness, outstanding chemical resistance, and good dimensional stability.
PEEK plates are widely utilized in industrial sectors demanding performance under harsh environmental conditions (e.g., high temperature, high pressure, corrosion, radiation).
Common Classifications of PEEK Plates and Sheets
According to diverse application requirements, PEEK plates are commonly modified through the addition of reinforcing fillers to optimize specific properties. Key classifications include:

Unfilled PEEK Plate (Natural PEEK)
These plates are manufactured from pure PEEK resin without added reinforcing fibers or fillers. They exhibit the inherent, well-balanced properties of PEEK, including good toughness, ductility, excellent electrical insulation, and availability in FDA-compliant grades for food and medical contact applications.

30% Glass Fiber Reinforced PEEK Plate
Uniformly compounded with 30% (by weight) short glass fibers within the PEEK resin. The inclusion of glass fibers significantly enhances the material's stiffness (modulus), mechanical strength, and creep resistance. It also reduces the coefficient of linear thermal expansion (CLTE), improving dimensional stability, particularly at elevated temperatures. Toughness is slightly reduced compared to unfilled PEEK.

30% Carbon Fiber Reinforced PEEK Plate
Uniformly compounded with 30% (by weight) carbon fibers within the PEEK resin. Carbon fibers provide higher stiffness and strength compared to glass fibers, coupled with excellent wear resistance and a lower coefficient of thermal expansion. A key characteristic is that the addition of carbon fiber makes the material conductive or anti-static; it is no longer an electrical insulator. This grade exhibits the highest hardness but may be more brittle than GF30 PEEK.
Key Classification Performance Data Comparison
The following table outlines typical physical property data for these three common PEEK plate classifications for reference purposes. Specific values can vary slightly based on grade and testing conditions. For precise data, please refer to the specific product Technical Data Sheet (TDS) provided by Dalian Oushida.
