polyether 砜
polyether is types high temperature resistance, 无定形 thermoplastic property engineering plastics , it is from 1983 year upper tool has long heat stabilized property and many 芳族砜 典 type property 质. it can in many 方面取代 metal, 玻 璃以 and and other material.
property can
in polyether many applications in, most main/primary is it can in long high temperature conditions lower use. ASTM D? 648 heat deflection temperature (HDT) can 达 400°F.
it can in -148?392°F scope/range inner maintain very good tough property and property. 玻璃化转变 temperature degree is 428°F. in 60?106Hi frequency rate scope/range inner and in high temperature conditions lower, its electrical property can maintain 不变.
in room temperature conditions lower, its mechanical properties and its it type polymer versus 似. it is types hard material, flexural modulus is 2757MPa, tensile impact strong/high degree is 160 ft．-lb／sq．inch. mechanical properties stability property can maintain to will hot deformation temperature degree. polyether ratio its it 无定形 thermoplastic property plastics tool has more good resistant ring force crazing property can. property most strong/high is ester, ketone and type. has 一定侵蚀 property is alcohol, 芳烃.
polyether tool has hydrolysis stability property and resistant usually use acid, alkali. add flame retardant still tool has very good flame retardant property. it USA food material tube/pipe 理局（ FDA ）认 can can in food industry in one-time or more use.
polyether mixed combined material can is transparent, can is transparent. it has multiple glass fiber strong/high product grade. its it filling material 例如矿 material and micro can by using/adopting.
processing
polyether can in generally injection molding and extrusion molding equipment upper processing. polyether tool has versus high melt processing temperature degree scope/range （ most high is 610?750°F）, this and it high heat deflection temperature (HDT) （400°F） has 关.
in melt processing front, must will its drying to water amount small 于 0．04％. this process can in 一 空 gas ring or material drying device inner formed, 300 °F drying 4 h or 350°F drying 2．5 h. is production low internal stress, high property can polyether products, injection molding mold temperature degree need to 300?350°F. inner flow property good, melt temperature degree is 725°F时, 0．08 in thick degree inner flow is 19 in.

ethylene - acrylic ester （EEA）
ethylene - acrylic ester （EEA） resin is polyolefin in tough property and degree most large 一族. it scope/range from type 橡胶, combined as hot bonding agent low melting point product, to type polyethylene (PE), tool has non 同寻常 tough degree and degree product. this category of resin is ethylene and acrylic ester random copolymer, usually structure is
acrylic ester separation is copolymer provide degree and property, usually polymer 15?30％（wt） content. and ethylene -醋 acid ethylene ester （EVA） versus ratio, is ethylene copolymer, EEA has more high heat stabilized property, belongs to non property degradation product, can processing conditions scope/range more wide.
processing and again made 厂常常 EEA and type polymer or engineering polymer combined in 一起, production 出 两 types resin advantages combined product.
chemical and property can
EEA resin is in 专门改装 high pressure polyethylene (PE) reaction device in free radical polymerization method production. acrylic ester content increase 时, copolymer will more tough, more soft/flexible, more has elastic property. high acrylic ester content resin property, increase surface absorption ink can force tool has bonding property 质.
and its it polyolefin 如LDPE versus comparison, EEA basic use property can has: for force fracture, impact, and bending fatigue has relatively strong/high resistant force; relatively high friction coefficient; relatively good low temperature property can and more low melting point. acrylic ester （EA） content rise high 时, copolymer upper use temperature degree has decline, transparent degree reduce.
market upper EEA usually is add modified sheet/slice resin, has a large amount of filler specialized mixed combined material, flame retardant mixed combined material and used as coating semi 导体材 material.
processing
processing EEA copolymer can using/adopting is tool has versus melt flow index LDPE design standards 挤塑. blow molding and injection molding equipment. type pressure melt temperature degree is 320°F; injection molding method temperature degree scope/range is 280?400°F, specific value according to melt flow index and acrylic ester content 而定. EEA copolymer processing 时无论 using/adopting pressure method, blow molding method or injection molding method processing, usually must use additives.
applications
