2、ACRYLONITRILE BUTADIENE STYRENE (ABS) WSS-M4D792-B1 MOLDING COMPOUND, HIGH HEAT RESISTANT, INTERIOR / EXTERIOR LIGHTING 1. SCOPE The material defined by this specification is a molded in color, high heat resistant injection molding compound based on acrylonitrile butadiene styrene (ABS) that has bee

3、n UV stabilized for unpainted interior applications or non-direct sunlight exposure in exterior applications. High heat resistant ABS is defined as must having a mean Vicat softening temperature range from 109 C to 115 C. 2. APPLICATION This specification was released originally for material used fo

4、r tail lamp housing and unpainted interior trim parts that require higher heat capability. 2.1 LIMITATIONS Material approved to this specification does not contain proper UV stabilizers for direct sunlight exposure in exterior applications. Therefore long term exposure to direct sunlight could cause

5、 chalking and loss of gloss. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 Many 4D resin specifications prior to 2011, identified certain req

6、uirements 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 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 This specification is bas

7、ed on virgin materials, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible. 3.1.3 The use of regrind is permitted, for economic / environmental reasons

8、, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Component and Allergen Requirements. Data must be included
