Polyether ether ketone resin (PEEK resin) is a new type of semi-crystalline aromatic thermoplastic engineering plastic prepared by condensation of 4,4’-difluorobenzopheneone and hydroquinone in the presence of alkali metal carbonate with diphenylsulfone as solvent. It's high temperature thermoplastic plastic with high glass transition temperature( 143℃ )and melting point( 334℃ ). Its load thermal deformation temperature is as high as 316℃(30% glass fiber reinforced or carbon fiber reinforced PEEK). It can be used in 250℃ for a long time. Compared with other high temperature resistant plastics like PI, PPS, PTFE and PPO, the upper limit of operation temperature of PEEK is nearly 50℃ higher.
Junhua PEEK concentrates on polymerization of PEEK resin formally to provide stronger raw material safeguard for PEEK parts and profiles and create particular advantage based on ten years’ accumulated experience in PEEK industry. At the same time, research, development and production of parts and profiles can also promote that of resin polymerization. Our cost and technology advantage is outstanding because Junhua is an enterprise with whole industrial chain includes PEEK resin polymerization, modified granulation, continuous extrusion of profiles and research, development and production of finished parts.
