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.
