2、DE (PPS) MOLDING COMPOUND, WSS-M4D1063-A2 IMPACT MODIFIED, LOWER MODULUS 1. SCOPE The materials defined by these specifications are flexible, thermoplastic polyphenylene sulfide injection molding compounds. The materials are useful in applications where flexible, high impact nylon has insufficient h
3、eat resistance. 2. APPLICATION WSS-M4D1063-A1 This specification was released originally for higher temperature clips and fasteners. WSS-M4D1063-A2 This specification was released originally for higher temperature cable ties, the lower modulus allows hand assembly. 2.1 LIMITATIONS These material are
4、 not applicable for mold in color, weatherable parts. 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 docu
5、ments. The 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 +/
6、- 5% relative 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 th
7、e designated 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.

The specificati
9、on 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. 3.4.2 This specification is based on virgin material and does not allow the addition of recycled content (PIR/PCR). 3.4.3 The use of regrind is permitt
10、ed, for economic / environmental reasons. Part manufacturers using this specification must complete DV and PV testing with the allowable amount of regrind and the maximum allowable regrind content must be specified on the engineering drawing. Any changes to what is specified on the drawing (no speci
11、fic amount implies zero regrind) must be approved by Materials and PD Engineering through the formal Ford Motor Company process (SREA) or Engineering Notice. 3.4.4 Ford Materials Engineering may request a Control Plan and Certificate of Analysis (C of A) containing lot testing requirements which mus
12、t include, but are not limited to: Melt Flow Rate Impact Strength, Notched Charpy at 23 C Tensile Modulus 3.5 SAMPLE PREPARATION All tests shall be carried out on production materials manufactured from the production process unless correlation to a non-production process has been reviewed and approv
13、ed by Ford Materials Engineering. Unless otherwise specified all tests shall be carried out on injection molded, one-end gated test specimens. The test specimens A and D shall be molded using molding conditions defined in ISO 25137-2. See Table 1 for the number of samples required. Specimens shall b
