PCTG是一种非结晶性共聚酯,可预防结晶化,进而改善加工制造和透明度;用PCTG所做出来的工艺产品透明度高,抗冲击性能优异,它可以用多种加工法式使其成型,如:注塑、挤出、吹塑及吸塑等成型方法.PCTG热成型性能出众,坚韧性好,耐候性优秀,耐化学性能优异,环保(FDA食品接触),经济性(比PC板便宜).正是PCTG具有这些独特的性能让它在板、片材和异型材方面得到很好的应用.下面就为大家具体介绍一下美国伊士曼PCTG GX100工程塑料的各方面性能与应用.


PCTG热成型性能:
PCTG板材易于生产出造型复杂及拉伸比大的制品.而且,与PC板和抗冲改性的压克力不同,这种板材无须在热成型加工前进行预干燥处理.与PC板或压克力相比,其成型周期短,温度低,成品率更高.


PCTG坚韧性:
PETG板材在加工、运输和使用过程中具有足够的承受能力,有助于防止破裂.PCTG挤出板材通常比通用亚克力坚韧15至20倍,比抗冲改性的亚克力坚韧5至10倍.


PCTG耐候性:
PCTG板材耐候性优秀.它可以防止变黄,保持产品坚韧性.它含有紫外线吸收剂,可共挤成一保护层,保护了板材免受紫外线的有害影响.


PCTG耐化学性能:
PCTG板材可以耐受多种化学品以及常用清洁剂.


PCTG环保性:
PCTG板材基材均为环保材料,符合食品接触管理要求.


PCTG经济性:
比PC板便宜,比亚克力耐用.

Tritan™ TX2000

共聚多酯

Eastman Chemical Company

Product Description:

Eastman Tritan™ TX2000 is an amorphous copolyester with excellent appearance and clarity. Its most outstanding features are excellent toughness, hydrolytic stability, and heat and chemical resistance. This new-generation copolyester can also be molded into various applications without incorporating high levels of residual stress. Combined with Tritan™ copolyester's outstanding chemical resistance and hydrolytic stability, these features give molded products enhanced durability in the dishwasher environment, which can expose products to high heat, humidity, and aggressive cleaning detergents. Tritan™ TX2000 copolyester may be used in repeated use food contact articles under United States Food and Drug Administration (FDA) regulations. Tritan™ TX2000 copolyester is certified to NSF/ANSI Standard 51 for Food Equipment Materials.
