Informations produit

Cristal™ 400 copolyester is a high flow product. It is designed and engineered specifically for cosmetics packaging

applications. With its unsurpassed color and clarity and an unmatched ability to mold thick parts with improved

gate aesthetics, Cristal™ is clearly a well suited copolyester for premium cosmetics packaging. Other outstanding

features of Cristal™ are excellent chemical resistance, high gloss, and improvements in processing such as faster

cycle times, and lower scrap rates. Cristal™ is also ideally suited for two-shot molding techniques due to its lower

processing temperatures, very slow crystallization rate, and flow characteristics.
