polyether ether ketone is large separation 子主链由芳基, ketone and ether formed property polymer, it is currently can large amount production poly ether ketone product types, 英文名称 is polyetherether ketone, 简称PEEK, separation structure is

polyether ether ketone separation structure

polyether ether ketone tool has hot solid property plastics heat resistant property, chemical stability property and thermoplastic property plastics molding processing property. polyether ether ketone also tool has excellent heat resistant property. its heat deflection temperature (HDT) is 160℃, use 20%~30% glass fiber reinforcement 时, heat deflection temperature (HDT) can improve/increase to 280~300℃. polyether ether ketone heat stabilized property good, in gas in 420℃. 2h情况 lower heavy is 2%, 500℃时 is 2.5%,500℃时才 generate significantly hot heavy. polyether ether ketone long use temperature degree is 200℃, in temperature degree lower, still can maintain relatively high tensile strength and flexural modulus, it also is types non solid material, has excellent long creep resistance and fatigue resistance can.

polyether ether ketone electrical insulation property can non excellent, volume resistivity is 10~10Ω·cm. it in high frequency scope/range inner still tool has relatively small dielectric constant and dielectric loss. 例如, in 10Hz时, in it dielectric constant is 3.2, dielectric loss is 0.02.

polyether ether ketone chemical stability property non good, remove concentrated acid outer, for chemical agent non stability, make in relatively high temperature degree lower, still can maintain good chemical stability property. another, it also tool has heat resistant water property and resistant property. in 200~250 ℃ 蒸汽 in can long time use.

polyether ether ketone has very good flame retardant property, in usually ring lower very flame resistant 烧, make is 燃烧, amount and has gas 体 释放 amount is very low, low PTFE and other low amount polymer. in addition. it also tool has excellent resistant property. it for α射线, β射线, γ射线 抵 resistant can force is currently polymer/macromolecule material in most good. use it electrical products can resistant 1.1×10Gy γ射线.

polyether ether ketone in melting point above has good melt flow property and heat stabilized property. tool has thermoplastic property plastics type molding processing properties, therefore can use injection molding, extrusion, blow molding, lamination and other molding methods, also can filament, made film. although polyether ether ketone melt processing temperature degree scope/range is 360~400℃, is due to it hot separation understanding temperature degree in 520 ℃ above, it still tool has very wide processing temperature degree scope/range.

尽 tube/pipe polyether ether ketone development history is short short 二十几 year, is due to it tool has heat resistant property, chemical resistant property, resistant property and high strength, easy processing property, make it currently already in industrial, chemical industrial, electronics electrical appliances, machine table/sheet, automotive industrial and field/area in to application. especially is as is resistant thermal properties excellent thermoplastic property resin, it can used as high property can composite/compounding material 基体材 material.

modified

PEEK pure material property can difficult meet/satisfy different industry field/area different demand, in specialty as ring need for PEEK进行 modified, its main/primary has blending modified, copolymer modified, composite/compounding reinforcement modified, modified, nano modified and surface modified and other technology. through modified can increase PEEK certain property can, wear resistance, impact strong/high degree and other, from expand PEEK application scope, reduce material use cost, PEEK processing properties.

product features

resistant property, insulation property stability, hydrolysis resistant, resistant pressure, corrosion resistant, its composite/compounding material made as formed machine parts tool has lubricated 效果.

1: machine features PEEK is tough property and rigid property 兼备并取 balanced plastics. especially is it for 交变应 force excellent resistant fatigue is has plastics in most 出众, can and alloy material 媲美.

2:自 lubricated property PEEK in has plastics in tool has sliding features, combined 于严格 requirements low friction coefficient and resistant consumption applications use. especially is carbon 纤, 石墨各占一定 ratio/proportion mixed combined modified PEEK自 lubricated property can more 佳.

3: chemical resistant product property (corrosion resistant property)PEEK tool has excellent chemical resistant product property. in usually chemical product in, can solvent understanding or bad it has concentrated acid, it corrosion resistant property and versus 近.

4: flame retardant property PEEK is non stability polymer, 1.45mm thick sample, add flame retardant can to most high flame retardant standards.

5: resistant property PEEK resistant property very good, therefore can made formed very thin or electrical magnetic 线, can in conditions lower use.

6: fatigue resistance PEEK in has resin in tool has most good fatigue resistance.

7: resistant property resistant high can force very strong/high, ultra- general purpose resin in resistant property most good polystyrene (PS). can as formed γ辐照 agent amount 达1100Mrad时 still can maintain good insulation can force high property can.

8: hydrolysis resistant property PEEK and its composite/compounding material water and high pressure water gas chemical effect/influence, use this type of material as formed products in high temperature high pressure water in use still can maintain excellent features.
