Texto del producto

Eastar™ CN005 copolyester is a high flow product. Designed specifically for the unique requirements of luxury cosmetic packaging, our premier PCTA copolyester delivers unsurpassed color and clarity and a capability to mold thick parts with superior gate aesthetics. Other outstanding features of Eastar™ CN are excellent chemical resistance, high gloss, and process enhancements 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.
