Technical Data Sheet
Eastman Tritan™ Copolyester HM1040 Glass Filled


Applications
  • Appliances (food contact)
  • Consumer housewares - food contact (FC)
  • Consumer housewares-NFC
  • Small appliances non-food contact
Key Attributes
  • Contact clarity
  • Ease of processing
  • Excellent hydrolytic stability
  • Good chemical resistance
  • Good heat resistance
  • Good toughness
  • Increased modulus or stiffness

Product Description
Eastman Tritan™ HM1040 copolyester is a glass-reinforced version of Tritan (amorphous copolyester) that provides increased modulus and strength versus unreinforced versions. Tritan HM1040 contains 20% glass fiber as well as a mold release agent derived from vegetable based sources. Its most outstanding features are excellent chemical resistance, toughness, heat resistance, contact clarity, ease of processing, hydrolytic stability, and increased modulus or stiffness. Combined with Tritan™ copolyester’s outstanding chemical resistance and hydrolytic stability, these features give molded products improved modulus and strength in applications that are exposed to certain chemicals, aggressive cleaners, and disinfectants. Contact clarity is also advantageous for secondary operations such as laser welding.

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.
