Product Description

Eastman Cristal™ Renew copolyester 400-50 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 Renew 400-50 is clearly a well suited copolyester for premium cosmetics packaging. Other outstanding features are excellent chemical resistance, high gloss, and improvements in processing such as faster cycle times, and lower scrap rates. Cristal Renew 400-50 is also ideally suited for two-shot molding techniques due to its lower processing temperatures, very slow crystallization rate, and flow characteristics.

Eastman Renew polymers have been certified by International Sustainability & Carbon Certification (ISCC), a global, independent agency for tracking sustainable content in a variety of industries. Renew polymers are produced with ISCC certified circular content by mass balance allocation.

Renew polymers enable a brand to reduce consumption of fossil feedstock-based plastics, achieve sustainability targets without compromise, and be a fast mover in a growing market for sustainable consumer products.
