Product Details
Introduction
Polyetheretherketone (PEEK) is a high-performance semi-crystalline thermoplastic engineering plastic with excellent mechanical strength, high temperature resistance, chemical corrosion resistance and good electrical insulation. Its long-term use temperature can reach 260°C and it can maintain stable physical and chemical properties in extreme environments. It is widely used in aerospace, automotive, electrical and electronic, medical, industrial and energy fields, and is an ideal material to replace traditional metals and engineering plastics.
