SCOPE The materials defined by these specifications are 30% glass fiber filled thermoplastic injection m

3、olding compounds based on polypropylene with added UV stabilization and scratch additives for exterior use. 2. APPLICATION These specifications were released originally for material used in mold-in-color exterior applications, specifically for cowl top ventilator grills. Any color additives need to

4、be reviewed and approved by the raw material supplier and Ford Materials Engineering. The UV/process/heat stabilizers must be in the base resin from the material supplier, not in the color concentrate, specifically for mold-in-color applications at the press. 2.1 LIMITATIONS These materials should n

5、ot be used for painted applications since they contain performance additives that negatively affect paint adhesion. Production level materials must be used in preparing test parts / panels. The use of improper sample prep materials can influence test results. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENT

6、S 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 requirements with the symbol (s), which indicated that the mean and +/-

7、3 sigma values were to be reported. The specification minimum, maximum or range was established using 3 sigma values. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.2 These specifications are based on virgin materials, however materials with recycled content

8、as defined by WRS-M99P42-A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. 3.1.3 The use of regrind is permitted, for economic / env

9、ironmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Performance Criteria Parts using these specifications shall meet the appropriate performance specifications WSS-M98P13-C / Latest.
