Polyetheretherketone (PEEK) resin is a special engineering plastic with ultra-high performance issued in the late 1970s.
High-temperature resistance: PEEK material has a high glass transition temperature (Tg=143°C) and melting point (Tm=334°C), its thermal deformation temperature under load is as high as 316°C, the long-term use temperature is 260°C, and the instantaneous use temperature can be up to 300°C.
Toughness and rigidity: PEEK raw material has toughness and rigidity, especially the fatigue resistance under alternating stress is very outstanding, which is comparable to alloy materials.
Creep resistance: It has excellent performance and is the best creep resistance material for thermoplastic resins.
Self-lubrication (wear resistance): PEEK has excellent sliding properties and is suitable for occasions where low friction coefficient and wear resistance are strictly required; especially PEEK modified with carbon fiber, graphite and PTFE has excellent wear resistance.
Corrosion resistance: In addition to concentrated sulfuric acid, PEEK is insoluble in any solvent and strong acid and alkali, and it is resistant to hydrolysis and has high chemical stability.
Hydrolysis resistance: PEEK products can still work continuously for thousands of hours without obvious performance degradation when immersed in steam at a temperature of 250°C or in high-pressure water; among all engineering plastics, PEEK has the best water resistance Solubility and steam resistance.
Radiation resistance: It has extremely strong resistance to high-dose γ-ray radiation, and its mechanical properties can be completely preserved, surpassing the best radiation resistance of polystyrene in general resins, and can be used as a radiation resistance in nuclear equipment. Radiant parts.
Flame retardancy: PEEK has self-extinguishing properties, even if no flame retardant is added, it can reach the 94V-0 level (the highest level) of the UL standard.
Non-toxic: can be used in food hygiene, medical equipment, and other fields.
Fatigue resistance: Among all resins, PEEK has the best fatigue resistance.
Ease of processing: Although PEEK resin is a super heat-resistant resin, due to its advantages of good high-temperature fluidity and high thermal decomposition temperature, injection molding, extrusion molding, compression molding, blow molding, and melt spinning can be used. , rotary molding and powder coating, and other processing methods.
Compared with other special engineering plastics, PEEK has many significant advantages, high-temperature resistance of 260 degrees, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, wear resistance, not resistance to strong nitric acid, concentrated sulfuric acid, radiation resistance, super mechanical properties, widely used in aerospace, automobile manufacturing, electrical and electronic, medical and food processing and other fields.
