A. Schulman Diamond Centrex® 821 ASA Weatherable Polymers Injection Molding Grade (discontinued **)
Categories:	Polymer; Thermoplastic; ASA Polymer
Material Notes:	Centrex 821 resin is a medium-gloss, high-heat, medium-impact grade of ASA (acrylonitrile-styrene-acrylate). It is an injection molding grade with a good balance of physical properties, gloss and processing performance, along with good resistance to weather aging. Applications: Centrex 821 resin is used for exterior applications. As with any product, use of Centrex 821 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. A. Schulman has acquired Network Polymers & Diamond Polymers.
Key Words:	Weatherable Polymer
