Product Description
Eastman Tritan™ LX151HF is a high flow grade of an amorphous copolyester with excellent appearance and clarity. Eastman Tritan™ LX151HF has viscosity reductions of 40-50% relative to standard grades of Eastman Tritan™. Eastman Tritan™ LX151HF contains a mold release derived from vegetable based sources. Its most outstanding features are excellent toughness, hydrolytic stability, and heat and chemical resistance. Tritan™ LX151HF was developed for the cosmetic, fragrance, and personal care markets. Tritan™ LX151HF can easily be converted into articles for application in consumer and personal care markets by injection molding, extrusion blow molding, and injection blow molding.

Technical Disclaimer
Eastman makes no representation and disclaims any warranty that the material in any particular shipment will conform exactly to the values given.  Values as well as the performance of the final molded article may be affected by various factors such as the part design, mold design or tooling,  drying, processing conditions as well as coloring or pigmentation of the product. No warranty of merchantability or fitness for use is made, and nothing herein waives any of the Seller''s conditions of sale. You must make your own determination of the suitability of this product in your specific application due to the many factors (e.g. design, processing and conditions of use) that affect the performance of the final molded article.  Suitability of use should be evaluated with appropriate testing and analysis. The processing melt temperature and mold temperature refer to the actual resin melt temperature and actual mold surface temperature respectively. Consider overall resin residence time, part shot size utilization and part geometry to set appropriate processing melt temperature and mold temperature in order to minimize IV loss and maximize molded part performance.
