| Eastman Tritan™ HM1020 is a glass-reinforced version of Tritan (amorphous copolyester) that provides increased modulus and strength versus unreinforced versions. Eastman Tritan™ HM1020 contains 10% 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.&& |
