PEEK-G(pure resin particle) series - made from pure polyether ether ketone resin, has the best toughness and best impact resistance in all PEEK series. PEEK - G series can disinfect (steam，dry heat, ethanol and Y rays) with the most convenient way, and the composition of raw material conforms to the EU and the US FDA regulations on food adaptability. It is generally applied in medical, pharmaceutical and food processing.
Product introduction：
PEEK is a kind of semicrystalline aromatic polymer and its main chain of macromole is consist of aryl, ketone, and ether. PEEK has the properties of heat resistance, chemical stability as thermosetting plastics, and good processability as thermoplastics. At present, PEEK has been acknowledged as the best performance polymer material.
PEEK-G(pure resin particle) series - made from pure polyether ether ketone resin, has the best toughness and best impact resistance in all PEEK series. PEEK - G series can disinfect (steam，dry heat, ethanol and Y rays) with the most convenient way, and the composition of raw material conforms to the EU and the US FDA regulations on food adaptability. It is generally applied in medical, pharmaceutical and food processing.
