PCTG TRITAN TX1001 产品说明:
Eastman Tritan? TX1001 is an amorphous copolyester with excellent appearance and clarity. EastmanTritan? TX1001 contains a mold release derived from vegetable based sources. 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? TX1001 copolyester may be used in repeated use food contact articles under United States Food and Drug Administration (FDA) regulations. Tritan? TX1001 copolyester is certified to NSF/ANSI Standard 51 for Food Equipment Materials and is also certified to NSF/ANSI Standard 61 - Drinking Water System Components-Health Effects.

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用途:
板、片材:
使用常规的成型方法,可以制备1~25.4mm厚的透明材料,具有突出的韧性和高抗冲击强度,其抗冲击强度是改性聚丙烯酸酯类的3~10倍,成型性能优异,冷弯曲不泛白,无裂纹,易于印刷和修饰,广泛应用于室内外标牌、储物架、自动售货机面板、家具、建筑及机械挡板等。
PCTG卡主要应用于欧洲,但在北美、亚洲也得到了越来越多的应用。原因是具有很宽的加工范围,高的机械强度和优异的柔性,比起PVC透明度高,光泽好,容易印刷并且具有环保优势。
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。
