SCOPE The material defined by this specification is a low gloss, medium impact, rigid thermoplastic polyolefin elastomer (TPO) injectio
3、n molding compound, mineral (talc) filled, UV stabilized and high scratch resistant for interior use. 2. APPLICATION This specification was released originally for material used for an unpainted instrument panel with a non-seamless passenger airbag. 2.1 LIMITATIONS This material should not be used a
4、s an instrument panel substrate with a seamless passenger airbag. This material is not to be used in applications requiring painting because it contains internal anti-scratch additive. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must confo
5、rm 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 +/- 3 sigma values were to be reported. The specification minimum, maximum or r
6、ange was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test to meet specification limits. 3.1.2 This specification is based on virgin materials. Materials with post-consumer, post industrial, or repolymerised recycled materials as defin
7、ed by WRS-M99P42-A1 are preferred and should be used whenever feasible. 3.1.3 The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in Ford Engineering CAD and Drafting Standard E-4. 3.1.4 Materials used in interior applications must meet the requirement
8、s outlined in WSS-M99P2222-C1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package.
