PEEK Plastic Pellets

Natural PEEK plastic pellets for injection molding and high-performance engineering applications

Product Overview

PEEK (Polyether Ether Ketone) is a high-performance, semi-crystalline thermoplastic with exceptional heat resistance, mechanical properties, chemical resistance and dimensional stability. SZHL supplies high-quality PEEK resin pellets suitable for injection molding, extrusion and other processing methods. PEEK is widely used in aerospace, automotive, electronics, medical and industrial fields.

Available Specifications

  • Standard Grade: General purpose, excellent comprehensive properties
  • Glass Fiber Reinforced: 10% / 30% / 40% – higher strength, higher modulus
  • Carbon Fiber Reinforced: 10% / 30% – higher stiffness, excellent wear resistance
  • Various grades and custom formulations are available.
