The PEEK English name: Polyetheretherketone; Chinese name: polyether ether ketone; have excellent dielectric properties of the material when the temperature reaches 260 degrees. And to resist the energy ray irradiation. PEEK is from 4,4 '- difluoro benzophenone and hydroquinone in the presence of alkali metal carbonate, diphenyl sulfone as solvent for the condensation reaction of a new type of semi-crystalline aromatic thermoplastic engineering plastic. 
 A, PEEK plate PEEK bar features: 
 PEEK plate / rod aromatic crystalline thermoplastic polymer material, the melting point of 334 ° C with high mechanical strength, high temperature resistance, impact resistance, flame retardant, acid and alkali, hydrolysis resistance, wear resistance, fatigue resistance, radiation and good electrical properties. 
 ● load hot temperature resistance of PEEK sheet / bar: it has a high melting point (334 ° C) and glass transition temperature (1 43), the continuous use temperature of 260 ° C, and the 30% GF or CF reinforced grades variant temperatures up to 316 ° C. 
 The mechanical properties of PEEK Sheet / Bars: it has good toughness and rigidity, it has comparable with the alloy material of the alternating stress the excellent fatigue resistance. 
 PEEK sheet / bars, self-lubrication (corrosion resistance): it has excellent sliding properties, suitable for consumption on the low coefficient of friction and abrasion demanding circumstances. 
 PEEK Sheet / bars, chemical resistance: its corrosion resistance and nickel steel similar, good chemical resistance, especially in high temperature conditions, more than the polyimide acid. 
 Flame resistance of the PEEK sheet / bar: it is very stable polymer, 1.45mm thick samples, without any flame retardant can achieve the highest flame retardant standards. 
 ● PEEK sheet / bars, radiation resistance and stripping resistance: It has good resistance to radiation, and stripping resistance, it can be used to make special use of magnet wire. 
 ● fatigue resistance of PEEK sheet / bar: it has the best fatigue resistance in all resin. 
 ● hydrolysis of PEEK Sheet / Rods: products of its composite material made of the continuous use of high temperature and high pressure water can still maintain good performance. 
 PEEK Sheet / bars, ease of processing: at high temperature with good mobility, high thermal decomposition temperature, can be injection molding, compression molding, extrusion molding, blow molding, melt spinning processing manner. 
 PEEK sheet / bar insulation stability: it has good electrical insulation properties, and maintain the high temperature range. Dielectric loss at high frequencies is also very small. 
 ● the wear resistance of PEEK sheet / bar: its good wear resistance is equivalent to the polyimide. 
 Two, PEEK plate PEEK rods application areas: 
 PEEK has many advantages mentioned above, a wide range of applications in many fields of petrochemical, electronics, electrical, instrumentation, machinery and automotive, health care, aerospace, military, nuclear energy. For example: 
 More mature applications are: air compressor piston rings, thrust ring, ring choke valves, cage bacteria valve, star wheel, seal rings, valve seats, bearings, oil lubricated bearings, magnetic pump isolation units, electrodes, gears, screws, magnet wire, radiation shutters, microwave digestion tank, wafer carriers, etc. 
 Three, PEEK plate PEEK bar size and color: 
 Plate: thickness x width to length = ~ 100mm x 500/620/1000mm x 1000mm; 
 Bars: diameter x length = ~ 200mm x 1000mm 
 Color: gray brown / black / gray / gray soil / red
