2、(PP) WSS-M4D865-B3 40% LONG GLASS FIBER REINFORCED, STRUCTURAL, NON UV-STABLE 1. SCOPE The material defined by this specification is an injection molding compound composed of a polypropylene matrix, with 40% by weight long glass fiber reinforcement with typical fiber length between 9-16 mm. 2. APPLI
3、CATION This specification was released originally for material used for bolsters. 2.1 LIMITATIONS This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material su
4、ppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). Note: 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. Th
5、e 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 to establish specification limits. 3.1.1 This specification is based on virgin materials, however materials with recycled content as define
6、d 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. The use of regrind is permitted, for economic / environmental reas
7、ons, with compliance as indicated in WSS-M99P1111-A. 3.1.2 Performance Criteria: Parts using this specification shall meet the appropriate performance specification WSS-M15P50-B/latest. 3.1.2 Processing Criteria: Proper processing parameters and equipment should be used to preserve maximum fiber len
