PEEK Granules
PEEK resin granules are unfilled, semi-crystalline thermoplastic pellets in light amber to beige color. They offer outstanding heat resistance (continuous service temperature up to 260°C), excellent chemical inertness, ultra-low moisture absorption (<0.5%), and superior electrical insulation. As the base grade for all PEEK formulations, pure resin delivers high toughness, dimensional stability, and recyclability, compatible with extrusion, injection molding, and compression molding processes.
