美国伊斯曼高流动PCTG Tritan LX150HF
Eastman Tritan™ LX150HF is a high flow grade of an amorphous copolyester with excellent appearance and clarity. Eastman Tritan™ LX150HF has viscosity reductions of 40-50% relative to standard grades of Eastman Tritan™. Its most outstanding features are excellent toughness, hydrolytic stability, and heat and chemical resistance. Tritan™ LX150HF was developed for the cosmetic, fragrance, and personal care markets. Tritan™ LX150HF can easily be converted into articles for application in consumer and personal care markets by injection molding, extrusion blow molding, and injection blow molding.
