高流动 DS1900HF 美国伊士曼 PCTA 抗化学 食品接触 电器用具
DuraStar™ DS1900HF
Thermoplastic Polyester
Eastman Chemical Company
产品说明：
Durastar™ DS1900HF polymer is a high flow grade of Durastar™ . Durastar™ DS1900HF flow lengths are increased 20-40% relative to Durastar™ DS1000 as shown by spiral flow testing. Other outstanding features of Durastar™ are easily maintained such as excellent appearance and clarity, good physical properties, chemical resistance, and easy processing. This high flow product is especially suited for those applications utilizing thin-walled intricate tools. Under existing United States Food and Drug Administration (FDA) regulations, Durastar™ DS1900HF may be used in food contact articles which comply with the specifications and conditions of use in 21 CFR 177.1240.
