Technical Data Sheet
Eastar™ DG011 Glass Filled Polyester

Key Attributes
  • Contact clarity
  • Ease of processing
  • Excellent hydrolytic stability
  • Good chemical resistance
  • Good heat resistance
  • Good toughness
  • Increased modulus or stiffness

Product Description
Eastar™ copolyester DG011 is a glass-reinforced amorphous copolyester that provides increased modulus and strength versus unreinforced versions. Eastar™ copolyester DG011 contains 10% glass fiber as well as a mold release agent. Its most outstanding features are excellent chemical resistance, toughness, heat resistance, contact clarity, ease of processing, hydrolytic stability, and increased modulus or stiffness. 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.
