Technical Datasheet | Supplied by Eastman
Eastar™ Copolyester CN005 by Eastman is a high flow polyester grade. It has high gloss appearance along with excellent clarity, color and ease of processing. It possesses good colorability, stiffness and toughness along with excellent impact strength and chemical resistance. It is converted by injection molding and has the ability to mold thick parts with improved gate aesthetics and is also suited for two-shot molding techniques due to its lower processing temperatures, very slow crystallization rate, and flow characteristics. It is used in applications such as premium cosmetics/personal care packaging, compacts, jar and jar caps, fragrance caps and packaging, lipstick containers and personal care bottles.
