Product Description
Eastman DN500 copolyester is a high flow product designed and engineered for many different applications. With its excellent color and clarity and its ability to mold thick parts with improved gate aesthetics, DN500 is clearly a well-suited copolyester for many applications. Other outstanding features are excellent chemical resistance, high gloss, and improvements in processing such as faster cycle times, and lower scrap rates. DN500 is also ideally suited for two-shot molding techniques due to its lower processing temperatures, very slow crystallization rate, and flow characteristics.
