Black Specks Comparison
Eastman Tritan™ copolyester can be processed similar to polycarbonate (PC) but with less risk of undesirable—and unsightly—black speck formation.
A stagnant area in an injection molding barrel can cause PC to char, resulting in black specks in molded parts. Tritan, however, does not have this propensity to char.
Black specks can be expensive for device manufacturers, particularly when hospitals or clinics reject entire lots of devices because of defects.
