PCTG TRITAN EX401 产品说明：

Tritan™ EX401, specifically developed for the Infant Care market, is an amorphous copolyester with excellent appearance and clarity. Tritan™ EX401 contains a mold release derived from vegetable based sources. Its most outstanding features are clarity, excellent toughness, hydrolytic stability, and heat and chemical resistance. Tritan™ EX401 meets infant care sterilization requirements via boiling water or microwave steam sterilization. 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 agents.

Tritan™ EX401 can be converted into parts using injection molding, injection stretch blow molding (ISBM), and extrusion blow molding techniques.

Tritan™ EX401 copolyester may be used in repeated use food contact articles under United States Food and Drug Administration (FDA) regulations. Contact Eastman representative for details on global food contact regulatory clearances.

Eastman Tritan™ EX401 copolyester is included in Eastman Chemical Company's Customer Notification Procedure which details our policy for customer notification when significant changes are made in Tritan™ EX401 sold into the infant care market. This procedure provides the infant care industry an added layer of confidence in the consistent quality and performance of Tritan.

PCTG 一种透明塑料，是一种非晶型共聚酯，PCTG常用的共聚单体为1,4-环己烷二甲醇(CHDM)，全称为聚对苯二甲酸-1,4-环己烷二甲醇酯。它是由对苯二甲酸(PTA)、乙二醇(EG)和1,4-环己烷二甲醇(CHDM)三种单体用酯交换法缩聚的产物，与PET比较多了1,4-环己烷二甲醇共聚单体，与PCT比多了乙二醇共聚单体，因此，PCTG的性能和PET、PCT大不相同。 PCTG是一种非结晶型共聚聚酯，随着共聚物中CHDM的增加，熔点下降，玻璃化温度上升，结晶度下降，最后形成无定形聚合物。PCTG中CHDM的含量大于50%。

PCTG特性:

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。

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。

耐候性:

PCTG板材提供了优秀的耐候性。它可以保持产品的坚韧性，防止变黄。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。

加工简便:

PCTG板材可进行锯切、模切、钻孔、冲孔、剪切、铆接、铣边以及冷弯，不至于破碎。表面的轻微刮痕可用热风枪来消除。溶剂粘接亦是常规操作。它比通用压克力、抗冲改性压克力或PC板更易于加工，并可进行植绒、电镀、静电等加工处理。

优秀的耐化学性能

PCTG板材可以耐受多种化学品以及常用的清洁剂。

环保: PCTG板材基材均为环保材料，符合食品接触管理要求。

经济性: 比压克力经久耐用。
