 一, what is PEN?

PEN is poly 萘二甲 acid ethylene glycol ester 简称, is 由2,6-萘二甲 acid ester （NDC） or 2,6-萘二甲 acid （NDA） and ethylene glycol （EG） polycondensation formed types new excellent polyester.

PEN chemical structure and PET versus 似, different in separation in PEN由 rigid property more large ring PET in ring. ring structure make PEN ratio PET tool has more high material mechanical properties, gas retardant property can, chemical stability property and heat resistant, resistant outer 线, resistant and other property can.

due to its excellent gas retardant property can, chemical stability property, Teijin will PEN use manufacturing device! lower 图 示:

二, PEN and PET property can comparison

1, from resistant thermal properties upper 看: PEN 玻璃化转变 temperature degree to 113℃, 而PET has 67℃; PEN melting point, separation understanding temperature degree high 于PET;

2, rate 方面: PEN is 0.64%, PET is 0.75%;

due to its heat stabilized property and low rate, PEN ratio PET more combined used for industrial filament （注: industrial filament is versus for/regarding use filament 而言, applications is main/primary is industrial field/area use filament; generally 而言, industrial filament ratio use filament requirements more high ）.

3, in force property can 方面: PEN modulus is 170cN/dtex, PET is 97cN/dtex; in 150℃ conditions lower, PEN hot shrinkage rate has 3%, 而PET is 8%;

4, in chemical resistance can 方面: in 120℃, versus for wet degree 100% conditions lower, 15天 left right PET残留 amount is 0%; same time inner PEN残留 amount is 60%. in 80℃, quality separation is 5% NaOH solvent liquid in 浸泡, 50 small rear PET残留 amount is 30%; same time inner PEN残留 amount is 90%.

force property can excellent, chemical resistance strong/high, PEN also can use manufacturing day use tool. has has very high 档 感觉! lower 图:

upper is PEN and PET property can comparison 图:

versus ratio PET, PEN tool has

high modulus (Modulus, 175cN/dtex)

low shrinkage rate （Thermal Shrinkage, 6.2%）

130℃ hydrolysis 60% time long （Hydrolysis, 200hr）

heat stabilized （Thermal Stability, Tg=118℃）

low gas retardant rate （Gas Permeation）

1/2 crystallization time long （1/2 Crystallinity）

延伸 property small （Elongation）

综 upper 述: PEN more combined used for industrial field/area!

三, PEN fiber application

四, PEN production enterprise has which?

currently full production PEN enterprise has Teijin group, 东洋纺, Mitsubishi chemical, 钟纺, UniPET, M&G（ acquisition Shell company PET, PEN事业）, KOSA, DuPont and Kolon and other is more polyester related enterprise.

1, Teijin 株式会社

Teijin 株式会社 is Japan 著名 跨国 company, is Japan textile 界巨头之一. formed day 期于1918 year 6 month 17 day; lower company 153家, its in Japan inner 59家, outer 94家. business covering high property can fiber and composite/compounding material, electronics material and chemical product, medical use product, fiber product and 零售, IT and other. 1990 year 5 month  PEN“Teonex” film achieve industry 化.

2, DuPont

DuPont company is 一家以科研 is full property enterprise, provide can improve/increase type in material and 营养, 保健, clothing/apparel, and construction, electronics and and other active field/area quality solution 之道. DuPont company formed 立于1802 year, in full 球70 国家经营 business, has 员工79,000 more 人.

3, 东洋纺

1882 year, 东洋纺 as is textile company, 开始 " fiber 事业". 历经 一 世纪, 顺应时代 development, in field/area （例: polymerization, modified, molding processing, material ） in, patent technology, large force development " film ・ machine can resin "" industry material ""生命 can 续" and other field/area.

4, Mitsubishi chemical

Mitsubishi chemical company is Japan most large chemical company, Mitsubishi formed company and Mitsubishi has company 于1994 year 10 month 1 day combined formed. company through its main/primary provide its product: function material and plastics product （包括信息 and electronics product, chemical products, made 药）; chemical industry; carbon and product.

5, UniPET

USA company, 专注于PET, PEN industrial manufacturing; main/primary supply is Europe and 北美 区

6, M&G

currently is world most large packaging use PET supply 商, year production capacity to 165 10,000 tons / year.

7, KOSA

USA day use product, polyester fiber, polymer and in product and other polyester product production 商.

五, PEN new 进展

in future, PEN fiber application trend has:

1, PEN fiber tool has high modulus, excellent heat stabilized property, resistant wet hot property and resistant alkali property, therefore by used as reinforcement material, used for 轮胎帘子线, belt/tape, made tube/pipe and other

2, as is more application, PEN fiber used for device film. in 不久 will, PEN fiber used for plastics.

3, new PEN tool has excellent heat stabilized property, 期望拓展 its new 应 use field/area
