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&＃39;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.

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。
坚韧性
PCTG板材的挤出板材通常比通用压克力坚韧15至20倍，比抗冲改性的压克力坚韧5至10倍。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。
