Polyetheretherketone (PEEK) – is a high-performance semi-crystalline high temperature plastic based on Victrex® PEEK 450G. As the most well-known and important member of the polyaryletherketone family of materials, this material has excellent wear resistance and excellent mechanical properties even under thermal loads. Excellent chemical resistance and high operating temperatures (up to 260°C) make TECAPEEK materials the most commonly used materials for highly pressurized parts. Its excellent dimensional stability, as well as high creep stability, make PEEK material suitable for the most complex machining parts.

Polyetheretherketone (PEEK) resin is a special engineering plastic with excellent performance, not only has excellent heat resistance. The heat distortion temperature is 160°C. When reinforced with 20% to 30% glass fiber, the heat distortion temperature can be increased to 280 to 300°C. The electrical insulation performance is excellent, and the volume resistivity is about 10 to 10Ω·cm. It still has a small dielectric constant and dielectric loss in the high frequency range. The chemical stability is also very good. Except for concentrated sulfuric acid, it is very stable to almost any chemical reagent, and it can still maintain good chemical stability even at higher temperatures.

The performance of PEEK pure material is difficult to meet the different needs of different industries. Therefore, PEEK needs to be modified in special working environments. The main methods include blending modification, copolymerization modification, composite reinforcement modification, filling modification, nanometer Modification and surface modification techniques. Modification can increase some properties of PEEK, such as wear resistance, impact strength, etc., thereby expanding the application range of PEEK, reducing the cost of materials, and improving the processing performance of PEEK. PEEK is commonly modified as follows:

• Glass fiber modification: 10%~30% glass fiber modification
• Carbon fiber modification: 10%~30% carbon fiber modification; carbon fiber, graphite and PTFE mixed modification;
• Ceramic modification: Ceramic+
• Resistance Modification: Conductive and Antistatic Modulation.
