Introduction and Features | Polyethylene Naphthalate (PEN) Resin Teonex® | Resin, Flame Retardant & Additives | Products & Serv

Polyethylene naphthalate (PEN) resin became popular in various fields after U.S. company Amoco Chemicals started commercial production of naphthalenedicarboxylic acid (NDC) , a raw material of PEN, in 1995. In 1964, 31 years before that, Teijin started development of PEN and commercialized as Teonex®. Since then, Teonex® has been popular as a functional material for industrial parts and wrapping materials for food and drugs, and still steadily increasing the area of applications. Teonex® is a crystalline thermoplastic polyester, a polycondensate of NDC as an acid component and ethylene glycol as a glycol component, manufactured in a process similar to that of polyethylene terephthalate (PET), a typical polyester. The property of Teonex® is considered superior to that of PET. Teonex® is crystalline resin, crystallized slowly, making it easier to shape transparent molded products. Teonex® has a superior chemical and scratch resistance compared to polycarbonate (PC) resin, a typical resin used in transparent molded products.

 

1. 1.High transparency.
2. 2.+50℃ of thermal resistance compared to PET.
3. 3.Higher hydrolysis resistance and longer life than PET.
4. 4.Higher chemical resistance than PET and PC.
5. 5.Reduces the concern for contamination thanks to low levels of outgassing and adsorption of organic materials.
6. 6.Absorbs ultraviolet radiation (up to 383nm) and protects contents inside.

Usage examples for application fields

• Returnable bottles
• Cosmetic containers
• Plateware
• Medical product containers
• Blending materials to improve PET performance (moisture barrier, gas barrier, heat resistance, UV ray absorption, etc.)
• Components that requires transparency, heat resistance, or chemical resistance

나프탈산 폴리에틸렌 [Polyethylene naphthalate] - PEN

나프탈산 폴리에틸렌 [Polyethylene naphthalate] - PEN 제품 목록 - 굿펠로우 코리아

일반 설명

폴리에스테르는 PET와 화학적으로 상당히 비슷하지만 온도 내성이 더 큽니다. 지금까지 이축 배향과 열안정화 필름으로만 이용했으며, 무색 반결정 또는 투명 결정 내지 약간 불투명한 폴리에스테르가 있습니다(후자는 굿펠로우에서 입수 가능). PET와 비교하면 150C가 아니라 190C에서 크게 줄어들기 시작하며, 105/130C가 아닌 155C에서 장기간 전기 사용이 인증되었습니다. 인장 강도는 비슷하지만 PEN 필름의 인장 계수는 더 높아 주위 온도에서 25%이며, 100~150C에서보다 몇 배 더 높습니다. 또한 자외선 내성과 차단성이 더 좋고, 알칼리나 매우 뜨거운 수성 상태에서 가수분해 내성이 더 강합니다. 그러나 더 비싸고 플렉스 수명이 더 짧습니다. 주로 전기와 전자 분야에서 필름용으로 사용됩니다.

POLYETHYLENE NAPHTHALATE FILMS

PEN Films

PROPERTIES

Polyethylene naphthalate (PEN) is a high-performance, crystal clear thermoplastic made from naphthalene-2,6-dicarboxylic acid and ethylene glycol. PEN has many attractive properties including high tensile strength, low heat shrinkage, excellent dimensional stability, low moisture absorption, and good retention of physical properties over a fairly wide temperature range. Its oxygen barrier, hydrolytic stability, and tensile strength surpass those of PET films. It also has superior UV resistance, excellent electrical properties, much lower heat shrinkage, good optical clarity and high gloss but only moderate moisture barrier properties. It has a relative high melting point and glass transition temperature (120°C), which makes it suitable for applications that require sterilization at high temperatures. Typical grades have a continuous service temperature of about 160°C.

Because of its higher price relative to PET, PE, and PP film, it is generally considered a specialty film.

APPLICATIONS

PEN surpasses PET in top end demanding applications and is often a good and less expensive alternative to more expensive high performance films. The performance of typical grades is between durable polyester and polyimides.

PEN is often an excellent choice for applications in the electrical and electronic industry. Some examples are flexible printed circuits, labels, laminates, electrical insulation, processing films for semiconductors, and optical displays. Due to its low oxygen permeability and very low heat shrinkage, it is particularly suited for products that are susceptible to oxidation and/or are exposed to heat (continuous electrical use up to 160°C).
