    供应新一代共聚聚酯材料-TRITAN™的详细描述：
    建议物料: PCTG (TX1001) 主要特性: 清澈透明 优良的抗冲击性 高耐化学性优良的可注塑性耐高温性良好的二次加工性强抗刮花性符合美国FDA和其它相关认证 安全、环保,不含双酚A 伊士曼 新一代共聚聚酯 Tritan™ 详细介绍: 由于人们对生活品质和健康的追求,市场对塑胶原材料的环保要求亦日益提高,例如 PC 水解后会产生 BPA (双酚-A)。近年来研究表明,人类(包括动物)如长期摄入微量的 BPA,极有可能对生殖系统产生不良影响,破坏性别比例的平衡,因此部分国家和地区已限制或禁用 PC。制造商面对环保方面的压力,正在寻找能替代 PC 的材料,Eastman 正是在这种市场背景下,开发出新一代共聚聚酯 Tritan™。 塑胶产品制造商也许对 Eastman 传统共聚聚酯并不陌生,例如 Eastar、Provista 等,它们固然有许多优点,也不含 BPA,但是Tg不高 (85℃左右),不能完全满足耐温高的要求,因此不能完全取代 PC。Eastman 新一代共聚聚酯 Tritan™ 不但完全继承了传统共聚聚酯的优点,而且耐温更高,加工更容易。 Tritan™的优点: 1). 不含BPA Tritan™ 在聚合生产过程中无 BPA 成分,在使用过程中也不会释放 BPA,符合环保要求及 FDA。 2). 清澈透明 透光率>90%,雾度

PCTG有PC的冲击强度，PMMA的透明度，不含双酚A。可用于婴儿奶瓶，耐开水蒸煮。
Eastman TritanTX1001 is an amorphous copolyester with excellent appearance and clarity.
EastmanTritanTX1001 contains a mold release derived from vegetable based sources. Its most
outstanding featuresare 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 Tritancopolyester’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.TritanTX1001 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.
