engineering plastics   is can as engineering material and metal manufacturing machine parts and other plastics . engineering plastics tool has excellent comprehensive property can, rigid property large, creep small, machine 械 strong/high degree high, heat resistant property good, electrical insulation property good, can in relatively chemical, material ring in long use, can substitute/replace metal as is engineering structure material use, 但 price relatively 贵, output/production volume relatively small.  
     engineering plastics also can separation is general purpose engineering plastics and specialty engineering plastics 两 type. front main/primary product types has polyamide (PA), polycarbonate (PC) , polyoxymethylene (POM) , modified polyphenylene oxide (PPO) and thermoplastic polyester large general purpose engineering plastics; rear main/primary is heat resistant 达150℃ above engineering plastics, main/primary product types has polyimide (PI), polyphenylene sulfide (PPS) , polysulfone (PSU) type, aromatic polyamide (PA), poly ester, poly ester, poly ether ketone, liquid crystal polymer (LCP) and fluorine resin and other.  
     engineering plastics property can features main/primary is:  
    (1) and general purpose plastics versus ratio, tool has excellent heat resistant and resistant property can, in temperature degree scope/range inner machine 械 property can excellent 良, as is structure material use; 
    (2) corrosion resistant property good, ring effect/influence relatively small, has good resistant property; 
    (3) and metal material versus ratio, easy processing, production efficiency high, can 简化程序, 节省费 use; 
    (4) has good dimensional stability and electrical insulation property; 
    (5) weight light, ratio strong/high degree high, tool has decrease 摩, wear resistance.  
     engineering plastics development history  
     engineering plastics is in 20世纪50 year to speed development. nylon 6 6 resin although in 1939 year already made formed 功并投入 production, 但当时 it main/primary used for manufacturing combined formed fiber, to 50 year breakthrough pure fiber applications, molding processing manufacturing plastics. engineering plastics true positive to speed development, is in 50 year rear 期 polyoxymethylene (POM) and polycarbonate (PC) development formed rear, it 们 出现 tool has especially heavy large 意义. due to polyoxymethylene (POM) high crystallization property, its excellent machine 械 property can, from 而首次 make plastics as is can substitute/replace metal material 而跻身于 structure material 行列. rear POM copolymer development formed and screw injection molding machine and, 进一步确立 engineering plastics in material field/area in important 位. 而 polycarbonate (PC) 则 is tool has excellent comprehensive property can transparent engineering plastics, application 广泛, is development most fast engineering plastics 之一, in engineering plastics field/area, its output/production volume and amount 仅次于 polyamide (PA) 而居第二位.  
    1961 year, USA DuPont company development formed polyimide (PI), 打开 通往 specialty engineering plastics development 道路. polyimide (PI) also polysulfone (PSU), polyphenylene sulfide (PPS) and polybenzimidazole (PBI) and other many heat resistant property engineering plastics development, for plastics industrial development generate deep effect/influence.  
     USA general purpose company 于1964 year will its development polyphenylene oxide (PPO) resin industrial production.  
    1980 year, UK ICI company development formed melting point high 达336℃ specialty engineering plastics polyether ether ketone (PEEK). PEEK tool has heat resistant property, resistant property and chemical resistant product property, can injection molding, 因而引起 人们 普遍关注. 以PEEK is 基体, through glass fiber or carbon fiber reinforced made composite/compounding material, already in aviation and field/area obtain application.  
    20世纪80 year in development formed hot liquid crystal polymer (LCP) is specialty engineering plastics development history upper also heavy large parts. liquid crystal polymer (LCP) heat resistant property excellent, use temperature degree can 达200℃ above, tool has reinforcement, high strength, high modulus, chemical resistant product and other features, melt viscosity low, molding 方便, in electronics industrial field/area tool has non vast application outlook/prospects.  
     engineering plastics application  
     and general purpose plastics versus ratio, engineering plastics in mechanical properties, resistant property, corrosion resistant property, heat resistant property and other can to more high requirements, but also processing more 方便并 can substitute/replace metal material. engineering plastics by widely used in electronics electrical, automotive, construction, office equipment, machine 械, aviation aerospace and other industry, 以塑代钢, 以塑代木 already formed is 国际流行 trend. engineering plastics already formed is world plastics industrial in growth speed degree most fast field/area, its development not only for 国家支柱 industry and high new technology industry 起 支撑 function, meanwhile 也推动传统 industry renovation and product structure adjustment.  
     engineering plastics in automotive upper application day increase more, main/primary used as 保险杠, 燃油箱, table/sheet sheet/plate, sheet/plate, 车门, lamp covers, tube/pipe, dispersion hot device and machine related parts and other.  
     in machine upper, engineering plastics can used for bearings, gears, filament 杠螺母, seals and other machine parts and housing/shell 体, cover/cap sheet/plate, 手轮, 手柄, solid parts and tube/pipe and other machine structural parts upper.  
     in electronics electrical appliances upper, engineering plastics can used for electrical cable 包覆, printing sheet/plate, insulation film and other insulation material and electrical appliances equipment structural parts upper.  
     in use electrical appliances upper, engineering plastics can used for electrical 冰箱, machine, device, electrical machine, electrical 风扇, device, electrical 熨斗, micro 波炉, electrical 饭煲, machine, combined equipment and lighting device tool upper.  
     in chemical industry upper, engineering plastics can used for hot device, chemical industry equipment and other chemical industry equipment upper and pipe/tube and tube/pipe parts, 阀门, and other chemical industry tube/pipe in.  
    我国 engineering plastics development current situation  
     due to automotive, electronics and construction and other industry development speed, currently, already formed is full engineering plastics demand growth most fast 国家. analysis, 随 国 inner 经济 不断 development, engineering plastics demand will 会进一步 to growth, engineering plastics industry development outlook/prospects separation vast. home appliances industry 说, 仅以冰箱, cold 柜, machine, and type small home appliances product year engineering plastics demand amount will 达60 10,000 tons left right. used for 通信基础设施 construction and iron 路, construction and other engineering plastics use amount more is 惊人, expected in the future year inner demand amount will to 450 10,000 tons above.  
    2010 year, engineering plastics amount 达244.3 10,000 tons, year-on-year growth 11%, is full demand growth most fast 国家;2011 year engineering plastics amount is 272 10,000 tons, year-on-year growth 11.34%. expected to 2013 year engineering plastics amount will to 337 10,000 tons, 2015 year to 417 10,000 tons.  
     engineering plastics has which?  
     engineering plastics main/primary polycarbonate (PC) (Polycarbonate,PC), polyamide (PA) (nylon,Polyamide,PA), polyoxymethylene (POM) (Polyacetal,PolyoxyMethylene,POM), polyphenylene oxide (PPO) (PolyphenyleneOxide,PPO), polyester (PET, PBT), polyphenylene sulfide (PPS) (PolyphenyleneSulfide,PPS), poly ester and other.
