2、 Technologies, LLC Page 1 of 3 ABS - POLYCARBONATE MOLDING COMPOUND, ELECTROPLATING ESB-M4D413-A2 AND PAINTING GRADE NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is an acrylonitrile butadiene styrene (ABS) and polycarbonate alloy which may be electroplated or pai
3、nted and exhibits good impact and heat resistance. ESB-M4D413 suffix designations correspond to former type categorization as follows: ESB-M4D413-A2 replaces ESB-M4D413-A1 Drawings specifying ESB-M4D413-A1 or ESB-M4D413-B1 do not require revision to reflect this new suffix classification. 2. APPLICA
4、TION This specification was released originally for material used in painted radiator grilles and electroplated mirror housings where high impact and/or heat resistance is required. 3.
