 一, polyimide (PI) overview

polyimide (PI) is separation structure has amine 基链节 芳杂 ring polymer/macromolecule combined material, 英文名Polyimide(简称PI) , is currently engineering plastics in heat resistant property most good product types 之一. PI as is types specialty engineering material, already application in aviation, aerospace, micro electronics, nano, liquid 晶, separation film, light and other field/area.

近, 各国都 in will PI research, development and utilizing 列入 21世纪 most has engineering plastics 之一. polyimide (PI), its in property can and combined formed 方面 突出 features, is as is structure material or is as is function property material, its large application outlook/prospects already to separation 认识, by is is " solution issues can 手"（protion solver）, is "没 has polyimide (PI) 就不会 has micro electronics technology ".

二, polyimide (PI) development history

三, combined formed methods

polyimide (PI) is separation structure has amine 基链节 芳杂 ring polymer/macromolecule combined material, 英文名Polyimide(简称PI), can separation is type PI, can solvent property PI, polyamide (PA) -酰亚 amine （PAI） and polyether amine （PEI）四 type.

按 combined formed methods can separation is polycondensation type and addition polymerization type:

1, polycondensation type polyimide (PI): polycondensation type polyimide (PI) already relatively less used as composite/compounding material resin, main/primary use manufacturing polyimide (PI) film and coating material.

2, addition polymerization type polyimide (PI): obtain application addition polymerization type polyimide (PI) main/primary has poly di 马 酰亚 amine and drop sheet/slice 烯基封端 polyimide (PI).

四, polyimide (PI) features has which?

as is use national defense material, polyimide (PI) tool has 6 large features:

1. high temperature resistance: high temperature resistance 达 400℃ above  , long use temperature degree scope/range -200～300℃, obvious melting point.

2. high insulation property can: 103赫 lower dielectric constant 4.0, dielectric loss 仅0.004～0.007, F至H grade insulation material.

3. excellent mechanical properties: 未 filling plastics resistant strong/high degree in 100Mpa above.

4.  self-extinguishing property: polyimide (PI) is self-extinguishing property polymer, rate low.

5.无毒: polyimide (PI) 无毒, 并经 起数千次消毒.

6. stability property: 一 polyimide (PI) product types solvent has machine solvent agent, for dilute acid stability, generally product types large hydrolysis resistant.

五, polyimide (PI) in plastics in 位

in heat resistant property, chemical resistance and force strong/high degree 方面, polyimide (PI) （PI） is material 金字塔 顶端.

六, polyimide (PI) main/primary production 商

to currently is 止 , polyimide (PI) already has  20  more large product types  ,随 its application scope expand large  , has polyimide (PI) product types will 会越 越 more.

国 outer production main/primary in in USA and Japan ,如 USA general purpose electrical company, DuPont company , Japan UBE company, Japan Kaneka corporation has company ;国 inner production main/primary is Shanghai combined formed resin research and long application chemical research. lower introduction lower most 知名 四 company:

1, development 历程

自1950 year USA DuPont company high temperature resistance polymer research, 1962 year aromatic polyimide (PI) in method production, is “H” type film. 1965 year in 俄亥俄州 塞克尔维尼建厂开始 large production, 并登记商 product is Kapton”, “Kapton” film has 3 types type type: H type, F type, V type, to 1980 year, production has 3 types Model/Grade 20 multiple specifications （7.5~125μm）,幅 wide 1500mm. through technology 改进, DuPont company also 于1984 year launch 3 types type Kapton film, separation is HN type, FN type, VN type, type polyimide (PI) film in currently production in already 占整 亚 amine film output/production volume 85%.

1983 year DuPont and Toray for semi combined 资建立东洋 product company, DuPont provide technology and raw materials ,专门 production Kapton”PI film, 1985 year 9 month start production, film wide degree is 1500mm. DuPont company in 1999 year 4 month investment China Taiwan, 1996 year formed base/seat polyimide (PI) （PI）厂太巨 company, formed is company main/primary shareholder, make formed is DuPont company in production PI film and flexible composite/compounding material is company.

2, manufacturing technology

DuPont “Kapton” is world product, its production technology process 路线, production methods, process equipment, raw materials control, film thick degree uniform property control methods and other is 严格保密. 据透露 DuPont company using/adopting method （循 ring belt/tape long 30m, wide 1.4m）. manufacturing process for Raw Materials pure degree requirements very high, process conditions control very 严格, production workshop is 封闭, production process full 部自动化 control, achieve 无人操 as. “Kapton” film resin combined formed main/primary using/adopting 均苯四甲 acid mono 体, manufacturing methods using/adopting hot amine ring and chemical amine ring types methods, separation used for 德克萨斯州 and 俄亥俄州两 polyimide (PI) film production 基.

1, development 历程

UBE industrial company in upper 世纪80 year 代初研 made formed types new type property polyimide (PI) 即联苯 type film, 包括UpilexR, UpilexS and UpilexC type series film, 打破 “Kapton” is table/sheet 以PMDA and DDE is raw materials manufacturing polyimide (PI) film market 20 year 局面. 二酐组 separation is 联苯四甲 acid 二酐, amine separation is 二氨基二苯 ether or for amine, according to amine structure different, and 二氨基二苯 ether combined 定位R type, and for amine combined 定位S type.

UBE development Model/Grade is UpilexR, production capacity 100万平方米/ year （ combined 80吨/ year ） PI film 于1983 year start production, 1985 year increase Model/Grade UpilexS. Upilex most large wide degree 1016mm, has Model/Grade: R type, S type, C type, thick degree specifications 25~125μm（ its in R type and C type has 7 types specifications ）. and Kapton versus ratio, UpilexS tool has high heat resistant property, relatively good dimensional stability and low moisture absorption property.
