Features
PEEK offers excellent performances. It can be used in many different areas due to is cheracteristics of flexible design and processing. Finished products include profiles (injection and extrusion), films, and coatings, etc. Compared with other special engineering plastics, it has more significant advantages. It can be resistant to +260 °C, excellent mechanical proper, good self-lubricating properties, chemical corrosion resistance, inflaming retarding, delamination resistance, wear resistance, radiation resistance and excellent mechanical properties.
Applications
PEEK has been widely applied in the fields of aerospace, automobile making, electronics, medical and food processing.
1. Outstanding mechanical strength;
2. Excellent fatigue and creep resistance;
3. Superior dimensional stability, with a heat deflection temperature as high as 315℃;
4. Excellent high-temperature resistance, with a continuous service temperature up to 260℃;
5. Outstanding flame retardancy and self-extinguishing property;
6. Superior radiation resistance (able to withstand nuclear gamma radiation and medical X-ray radiation);
7. Excellent chemical resistance (resistant to all chemical reagents except concentrated sulfuric acid and concentrated nitric acid, which are strong oxidants);
8. Superior processing characteristics (can be turned, milld, polished, etc.), capable of being processed by both dry cooling turning and liquid-cooled CNC, and using a long-term high-temperature stress relief method to ensure minimal internal stress in the profile.
