Kowalski, NA Controlled document at www.MATS Copyright 2017 Ford Global Technologies, LLC Page 1 of 9 POLYPROPYLENE (PP) COPOLYMER COOLING AGENT WSS-M4D741-B2 RESISTANT MOLDING COMPOUND 1. SCOPE The material defi

2、ned by this specification is a thermoplastic injection molding compound based on polypropylene copolymer. This material is resistant to engine coolant. 2. APPLICATION This specification was released originally for material used for overflow/degas bottles. 2.1 LIMITATIONS This material has low impact

3、 resistance at low temperatures. The material undergoes creep at elevated temperatures. Load limiters are required for fasteners and inserts may be necessary on outlets where clamping is required. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification is part of the Ford Co-Managed Buy (CMB) agreem

4、ent. Tier 1 Molders who are participating under the CMB agreement must use one the following approved sources (deviations require approval from Raw Materials Purchasing and Materials Engineering): Specification North American Programs European Programs WSS-M4D741-B21 Lyondell Basell / Equistar Hosta

5、len PP HP1886 TBD Molders not on the CMB program or regions without CMB are required to use materials listed on the Ford Approved Source List (ASL), and are encouraged to use the CMB sources listed above. Only the sources identified on the Approved Source List can be used when this specification is

6、listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. ENGINEERING MATERIAL SPECIFICATION WSS-M4D741-B2 Copyright 2017, Ford Global Technologies, LLC Page 2 of 9 3.2 CONDITIONING AND TEST

7、 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% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal. 3.3 INFRARED SPECTROPHOTOMETRY

8、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 designated material laboratory. The material supplier shall ensure that all future material supplied to the specification shall produce IR spectr

9、a 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 resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma v

10、alues 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 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

11、/PCR). 3.4.3 The use of regrind is permitted, 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

12、what is specified on the drawing (no specific 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 Material must be processed per Global Manufacturing Standard W-IMMS - Control of Plastic Injec
