PCTG types transparent plastics, is types non type copolymer ester, PCTG commonly used copolymer mono is 1,4- ring 己烷二甲 alcohol (CHDM), full is terephthalic acid ethylene glycol -1,4- ring 己烷二甲 alcohol ester. it is for 苯二甲 acid (PTA), ethylene glycol (EG) and 1,4- ring 己烷二甲 alcohol (CHDM)三 types mono use ester method polycondensation material, and PET comparison more 1,4- ring 己烷二甲 alcohol copolymer mono 体, and PCT ratio more ethylene glycol copolymer mono 体, therefore, PCTG property can and PET, PCT large same. PCTG is types non crystallization type copolymer polyester, copolymer in CHDM increase, melting point decline, 玻璃化 temperature degree upper rise, crystallization degree decline, most rear formed 无定形 polymer. PCTG in CHDM content large 于50%.

brief introduction

tool has relatively good viscous property, transparent degree, color, chemical resistant agent, and resistant force whitening can force. can very fast hot molding or extrusion blow molding. viscosity ratio acrylic （亚克 force ） good. PCTG is types non type copolymer ester, its products high degree transparent, impact resistant property can excellent, especially molding thick transparent products, its processing molding property can 极佳, can according to design 者 意图进行任意形状 design, can using/adopting extrusion, injection molding, blow molding and thermoforming and other molding methods, can widely used in sheet/plate sheet/slice 材, high property can shrinkage film, bottle use and type 材, product packaging and other market, meanwhile its processing properties excellent 良, can 进行常规 machine processing 修饰.

PET resin is binary alcohol （ ethylene glycol, EG） and binary acid （ for 苯二甲 acid, PTA） polycondensation formed type homopolymer polyester, copolymer polyester is use alcohol or acid modified polyester, has PETG, PCTG and PCTA以 and biodegradable copolymer polyester.

PCTG is types non crystallization property copolymer ester. in its production process in, due to 一定数 amount ethylene glycol by 1, 4-cyclohexane dimethanol（CHDM） 取代, can anti crystallization 化, improvement processing manufacturing and transparent degree. its products high degree transparent, impact resistant property can excellent, especially molding thick transparent products, its processing molding property can 极佳, can according to design 者 意图进行任意形状 design, can can using/adopting extrusion, injection molding, blow molding and thermoforming and other molding methods, can used for sheet/plate 材, sheet/slice 材, high property can shrinkage film, bottle use and type and other market, meanwhile its processing properties excellent 良, can 进行常规 machine processing 修饰.

key features

出众 hot molding property can

PCTG sheet/plate easy production type complex and tensile ratio large products. but also, and PC sheet/plate and impact resistant modified pressure force different, this type of sheet/plate must in hot molding processing front 进行预 drying 处理. and PC sheet/plate or pressure force versus ratio, its molding cycle short, temperature degree low, formed product rate more high.

坚 tough property: PCTG sheet/plate extrusion sheet/plate usually ratio general purpose pressure force tough 15至20倍, ratio impact resistant modified pressure force tough 5至10倍. PETG sheet/plate in processing, and use process in tool has 足够 承受 can force, has anti 止破裂.

weather resistance: PCTG sheet/plate provide excellent weather resistance. it can maintain product tough property, anti 止变黄. it has outer absorption agent, can formed 一保护层, sheet/plate 材免受紫 outer has effect/influence.

processing 简便: PCTG sheet/plate can 进行锯切, 模切, 钻孔, 冲孔, 剪切, 铆接, 铣边以 and cold 弯, 不至于破碎. surface light micro can use hot 风枪 消 remove. solvent agent bonding is 常规操 as. it ratio general purpose pressure force, impact resistant modified pressure force or PC sheet/plate more easy processing, can 进行植绒, electroplating, electrical and other processing 处理.

excellent chemical resistance can: PCTG sheet/plate can resistant multiple chemical product and commonly used agent.

environmental protection: PCTG sheet/plate 材基材均 is environmental protection material, combined food contact tube/pipe requirements.

经济 property: ratio pressure force resistant use.

main/primary applications

(1) sheet/plate, sheet/slice 材

use molding methods, can made 备1~25.4mm thick transparent material, tool has tough property and high impact resistance strong/high degree, its impact resistant strong/high degree is modified polypropylene (PP) acid ester type 3~10倍, molding property can excellent, cold bending 不泛白, cracks, easy printing and 修饰, widely used in inner outer 标牌, material 架, 自动售货 machine sheet/plate, furniture, construction and machine sheet/plate and other.

PCTG卡 main applications Europe, in to 越 越 more application. causes is tool has very wide processing scope/range, high machine strong/high degree and excellent flexible, ratio 起PVC transparent degree high, gloss good, easy printing and tool has environmental protection advantages.

(2) type 材

can molding pipe/tube or various type 材, its products hard, transparent, gloss good, pressure 不泛白, easy molding and rear processing 处理, combined environmental protection requirements, meanwhile combined USA FDA about/regarding food contact standards, widely used in construction decoration and material.

专门应 used for high property can shrinkage film, has large dry 70% most shrinkage rate, can made formed complex outer container packaging, tool has high thermoforming force, high transparency degree, high gloss, low degree, easy printing, easy 脱落, 存储时自然 shrinkage rate low advantages, used for material bottle, food and 化; product shrinkage packaging and electronics product and other shrinkage label. its in di toward tensile. PETG film suitable for high packaging, printing, electronics electrical appliances, cable 包扎, insulation material and various industrial field/area excellent 质基材. mono toward tensile PET, hot shrinkage film suitable for various 罐装, polyester bottle, various container and other outer use label. and PVC shrinkage film versus ratio, PETG shrinkage film also tool has environmental protection advantages.

improvement polyester material bottle tough property low 不足, especially combined manufacturing large amount thick transparent container, high degree transparent, easy 破碎, easy surface 修饰, to USA FDA about/regarding food contact standards, can used for food and medical products and other field/area. in plastics packaging 方面, EASTMAN company is day company production new type environmental protection plastics packaging bottle, is film as packaging material, its outer is black, in 颈部辅以 black belt/tape ring cover/cap, can retardant light 线, 隔绝空 gas, ensure quality, tool has in bottle 身破裂时 anti sheet/slice anti function, shrinkage property can excellent 越. day company using/adopting this type of packaging materials rear, Super Dry and Dunk啤酒 销 amount to large growth.

(3)化妆 product packaging

PCTG tool has 玻璃一样 transparent degree and 接近玻璃 density, very good gloss degree, chemical resistant 腐蚀, resistant impact, and easy processing, can injection molding, 注拉吹 molding and molding. also can generate 独特 形状, appearance and 特殊效果, ratio 如鲜亮 color, abrasion 砂, large 理石纹理, metal gloss and other. but also also can utilizing its it polyester, elastic property plastics or ABS进行 heavy plastics molding.

product has water bottle and bottle cover/cap, product bottle and bottle cover/cap, tube/pipe, box/case, remove agent packaging, powder bottle and 眼线笔 sleeve/set and other. PETG injection molding product has medical devices 如 滤 device, tube/pipe, tube/pipe 子连接 parts, 泵, 夹子以 and equipment and other. use device 皿如杯子, 沙拉碗, salt 罐, 胡椒罐 and other, tool has excellent transparent degree, gloss degree, good tough property, processing property and excellent color property.

PCTG is types. tool has high transparency degree, good tough property and impact strong/high degree, excellent low temperature tough property, high resistant property and good processing properties, excellent chemical resistance can. can 采取传统 extrusion, injection molding, blow molding and thermoforming and other molding methods processing. widely used in sheet/plate sheet/slice 材, high property can shrinkage film, bottle use and type market; can use production toys, use device and and other; through USA FDA about/regarding food contact standards, can used for food, 医药, product packaging and other field/area.
