SCOPE The material defined by this specification is a high impac
3、t thermoplastic molding compound based on a blend of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) for non-visible or painted applications. High impact PC+ABS is defined as being minimum 80% ductile at -30C. 2. APPLICATION WSS-M4D585-C1 This specification was released originally for m
4、aterial used for taillamp housing, in-mold film or wrapped aluminum substrate top finish panel of floor console, or painted finished molding. WRS-M4D585-C2 This specification was released originally for material used for non-visible interior applications. 2.1 LIMITATIONS WSS-M4D585-C1 This material
5、is not UV stabilized and should not be used for mold in color visible applications. WRS-M4D585-C2 This material is defined by 100% recycled PC +ABS thermoplastic molding compound for non-visible applications and is not UV stable. This material is not suitable for tail lamp housings. When used in dec
6、orated interior applications this material may require additional in process testing. Contact Materials Engineering for these requirements. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for
7、Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and 3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma data. For 2011
8、 and beyond, refer to Table 1 for number of samples required for each test to establish specification limits.
