2、1 FILLED, COLOR PIGMENTED, MOLDING COMPOUND, INTERIOR 1 SCOPE The material defined by this specification is a molding compound based on polypropylene copolymer, mineral filled, molded-in-color, for unpainted interior applications. 2 APPLICATION This specification was released originally for material

3、 used for interior trim applications. 2.1 LIMITATIONS This material should not be used in safety relevant locations such as locations in which vehicle crash forces or airbag deployment could cause part breakage. 3 REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and

4、 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 +/- 3 sigma values were to be reported. The specifica

5、tion 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 based on virgin materials, however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post

6、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 / environmental reasons, with compliance as indicated in For

7、d 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 Material/Component Requirements. Data must be included in material submission package. 3.1.5 Perf

12、g temperature, 15 +/- 2 C/minute cooling rate. The values of this specification are based on unannealed specimens. See Table 1 for the number of samples required. 3.3 APPEARANCE 3.3.1 Weathering Resistance Rating 4 min (FLTM BO 116-01, 2481.6 kJ/m2 exposure Specimen C from smooth polished mold, ISO

13、105-A02 / AATCC Evaluation Procedure 1) Every 526.4 kJ/m2 remove the samples from the weatherometer and allow them to cool for one hour. Conduct a tactile evaluation and report any tackiness. Visually evaluate and report any spewing or other exudation. After exposure the material shall show no fadin

14、g or color change in excess of the specified AATCC rating. In addition, there shall be no cracking, crazing or other deterioration. Use regional choice for initial approval and report the color house used. See Table 2 for additional color durability submission requirements. 3.3.2 Resistance to Scrat

15、ch and Mar (FLTM BO 162-01, Specimen I) Scratch Rating 2 at 2 N, max Whitening/Color Change Rating 1 at 7 N, max Marring Rating 2 at 2 N, max These values are derived from colored and grained samples in agreement with Materials Engineering.
