Eaton, NA Controlled document at www.MATS Copyright 2017, Ford Global Technologies, LLC Page 1 of 10 POLYPROPYLENE (PP) COPOLYMER, 22% MINERAL WSS-M4D556-B8 FILLED MOLDING COMPOUND, EXTERIOR 1. SCOPE The material

2、 defined by this specification is a 22% mineral filled thermoplastic injection molding compound based on polypropylene copolymer, with added UV stabilization and scratch additives for exterior use. 2. APPLICATION This specification was released originally for material used in mold-in-color exterior

3、applications, specifically for cowl top ventilator grills. Any color additives need to 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, specificall

4、y for mold-in-color applications at the press. 2.1 LIMITATIONS This material should not be used for painted applications since it contains performance additives that negatively affect paint adhesion. Production level materials must be used in preparing test parts / panels. The use of improper sample

5、 prep materials can influence test results. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The

6、 list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relat

7、ive humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms from initial material approval shall constitute the reference standard and shall be kept on file at the designat

8、ed material laboratory. The material supplier shall ensure that all future material supplied to the specification shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.4 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.4.1 Many 4D

9、 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 range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samp

10、les required for each test.
