Material Notes:

Centrex HGM resin is an exceptionally high-gloss grade of ASA (acrylonitrile-styrene-acrylate). This injection molding grade has excellent gloss retention, excellent resistance to chemicals and high heat, good resistance to weather aging, and a wide molding window.Applications: Centrex HGM resin is used in the automotive market for exterior applications such as mirror housings, cowl grilles, license plate pockets, exterior trim and radiator grilles. As with any product, use of Centrex HGM resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.Information Provided by Diamond Polymers, Inc. & Network Polymers, Inc.
