Product Description

Cristal™ 401 copolyester is a high flow product that contains mold release for ease of ejection. 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.
