供應新一代共聚聚酯材料-TRITAN™的詳細描述：
    建議物料: PCTG (TX1001) 主要特性: 清澈透明 優良的抗衝擊性 高耐化學性 優良的可注塑性 耐高溫性 良好的二次加工性 強抗刮花性 符合美國FDA和其它相關認証 安全、環保,不含雙酚A 伊士曼 新一代共聚聚酯 Tritan™ 詳細介紹: 由於人們對生活品質和健康的追求,市場對塑膠原材料的環保要求亦日益提高,例如 PC 水解后會產生 BPA (雙酚-A)。近年來研究表明,人類(包括動物)如長期攝入微量的 BPA,極有可能對生殖系統產生不良影響,破坏性別比例的平衡,因此部分國家和地區已限制或禁用 PC。製造商面對環保方面的壓力,正在尋找能替代 PC 的材料,Eastman 正是在這種市場背景下,開發出新一代共聚聚酯 Tritan™。 塑膠產品製造商也許對 Eastman 傳統共聚聚酯並不陌生,例如 Eastar、Provista 等,它們固然有許多優點,也不含 BPA,但是Tg不高 (85℃左右),不能完全滿足耐溫高的要求,因此不能完全取代 PC。Eastman 新一代共聚聚酯 Tritan™ 不但完全繼承了傳統共聚聚酯的優點,而且耐溫更高,加工更容易。 Tritan™的優點: 1). 不含BPA Tritan™ 在聚合生產過程中無 BPA 成分,在使用過程中也不會釋放 BPA,符合環保要求及 FDA。 2). 清澈透明 透光率>90%,霧度

PCTG有PC的衝擊強度，PMMA的透明度，不含雙酚A。可用於嬰儿奶瓶，耐開水蒸煮。
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.
