         polyether ether ketone （PEEK）

        poly(ether-ether-ketone) is in structure in has ketone and ether heavy mono 元 构 formed high poly material, specialty polymer/macromolecule material. tool has high temperature resistance, chemical resistant product and other material chemical property can, is type crystallization polymer/macromolecule material, melting point 334℃, soft 化点168℃, tensile strength 132～148MPa, can used as high temperature resistance structure material and electrical insulation material, can and glass fiber or carbon fiber composite/compounding made reinforcement material. generally using/adopting and aromatic binary shrink combined 而 一 type poly ether type high poly material.

        PEEK features

         high temperature resistance property polyether ether ketone PEEK tool has relatively high 玻璃化转变 temperature degree (Tg=143℃) and melting point (Tm=334℃), its negative heat deflection temperature (HDT) high 达316℃, long use temperature degree is 260℃, use temperature degree can 达300℃.

         machine features polyether ether ketone PEEK tool has rigid property and flexible, especially is for 交变应 force lower resistant fatigue property non 常突出, can and alloy material versus 媲美.

        自 lubricated property polyether ether ketone PEEK tool has excellent sliding features, combined 于严格 requirements low friction coefficient and wear resistant consumption applications combined, especially is use carbon fiber, 石墨, PTFE modified sliding grade PEEK wear resistance non excellent 越.

         corrosion resistant property concentrated acid outer, PEEK不 solvent 于任何 solvent agent and strong/high acid, strong/high alkali, but also hydrolysis resistant, tool has very high chemical stability property.

         flame retardant property polyether ether ketone PEEK tool has self-extinguishing property, make add flame retardant, can to UL standards 94V-0 grade.

         easy processing property due to PEEK tool has high temperature flow property good, hot separation understanding temperature degree also very high features, can using/adopting multiple processing methods: injection molding, extrusion molding, pressure molding and melt filament and other.

         polyether ether ketone （PEEK） application

         due to polyether ether ketone PEEK tool has excellent comprehensive property can, in many field/area can substitute/replace metal, and other 传统材 material. plastics high temperature resistance, lubricated, wear resistant loss and resistant fatigue and other features, make formed is most hot high property can engineering plastics 之一, it main applications aviation aerospace, automotive industrial, electronics electrical and medical devices and other field/area.

        (1) aviation aerospace field/area

         polyether ether ketone PEEK can processing formed various high degree machine parts, due to its hydrolysis resistant, corrosion resistant and flame retardant property can good, can processing formed machine inner / external parts and 火箭发动 machine many parts.

        (2) automotive manufacturing

         polyether ether ketone PEEK一直 formed used for automotive manufacturing 业, due to it tool has good resistant scratch property can, can substitute/replace metal (包括不锈钢, titanium) manufacturing machine inner 罩, automotive bearings, seals and sheet/slice and other.

        (3) industrial field/area

         polyether ether ketone PEEK due to tool has good mechanical properties, high temperature resistance, wear resistant consumption, can resistant high pressure, commonly used manufacturing pressure shrink machine sheet/slice, active ring, seals and other.

        (4) medical devices

         polyether ether ketone PEEK can in 134℃ lower 经受3000次循 ring high pressure 灭菌, this features can meet/satisfy requirements high, 需反覆 use and equipment manufacturing, add upper it resistant creep and hydrolysis resistant property, use it can manufacturing high temperature 蒸汽消毒 various medical devices. is important is PEEK无毒, light, corrosion resistant, is and 人体骨骼 most 接近 材 material, therefore can using/adopting PEEK代替 metal manufacturing 人体骨骼.

        (5) insulation material

        PEEK因 tool has excellent electrical properties, in high temperature, high wet and other poor conditions lower, polyether ether ketone insulation property can still can maintain, is electrical insulation material, especially is in semi industrial in to application.

        (6) new type engineering plastics

        PEEK is types new type engineering plastics, can used as high temperature resistance structure material and electrical insulation material, can and glass fiber or carbon fiber composite/compounding made reinforcement material.

        (7) modified polyether ether ketone (PEEK)

         has black carbon reinforcement conductive polyether ether ketone (PEEK), has color carbon reinforcement conductive polyether ether ketone (PEEK), has material reinforcement polyether ether ketone (PEEK), has glass fiber reinforced polyether ether ketone (PEEK), and PEEK resin. can using/adopting filling, blending, crosslinked, grafting and other methods for its modified, to property can more add excellent PEEK plastics alloy or PEEK composite/compounding material. 例如: PEEK and polyether blending can to more good force property can and flame retardant property;PEEK and PTFE blending made formed composite/compounding material, tool has wear resistance, can used for manufacturing sliding bearings, 动密封 ring and other parts;PEEK use carbon fiber and other filling modified, made formed reinforcement PEEK composite/compounding material, can large large improve/increase material hardness, rigid property and dimensions stability property and other.
