Product Description:Eastar CN005 copolyester is a high flow product. It is the first copolyester resin from Eastman that has been designed and engineered specifically for cosmetics packaging applications. With its great color and clarity and ability to mold thick parts with improved gate aesthetics, Eastar CN is clearly the most suited copolyester for premium cosmetics packaging. Other features of Eastar CN are excellent chemical resistance, high gloss, and improvements in processing such as faster drying times, faster cycle times, and lower scrap rates. Eastar CN is also ideally suited for two-shot molding techniques due to its lower processing temperatures, very slow crystallization rate, and flow characteristics. This product has been GREENGUARD INDOOR AIR QUALITY CERTIFIED?.
