PEEK Plates - Production of Different Grades and Specifications of PEEK Materials

PEEK (Polyetheretherketone) plates are semi-finished profiles made from high-performance thermoplastic PEEK resin through extrusion or compression molding processes. These plates and sheets provide flat materials with specific thicknesses, serving as the foundation for subsequent precision machining (such as milling, turning, drilling) to manufacture various high-performance engineering components.

Advantages of PEEK Plates

Excellent high-temperature resistance
Outstanding mechanical properties
Chemical resistance
Easy to machine
