2、D WSS-M4D706-B1 MOLDING COMPOUND 1. SCOPE The material defined by this specification is an injection moldable thermoplastic heat stabilizer, impact modified molding compound based on polyamide 66. 2. APPLICATION This specification was released originally for material used for carbon canisters. 2.1 L
3、IMITATIONS This material absorbs and retains moisture. Part design and tolerances must accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material does not contain UV stabilizers, long term exposure to direct su
4、nlight will cause chalking and loss of gloss. This material is not suitable for direct long term exposure to engine coolant, or direct exposure to strong acids or bases. It is not suitable for use above 150C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and p
5、art 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 specificati
6、on minimum, maximum or range was established using 3 sigma values. For 2011 and beyond, refer to Table 1 for number of samples required for each test to establish specification limits. 3.1.2 This specification is based on virgin materials, however materials with recycled content as defined by WRS-M9
7、9P42-A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically 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.

8、GINEERING MATERIAL SPECIFICATION WSS-M4D706-B1 Page 2 of 6 Copyright 2013, Ford Global Technologies, LLC 3.1.4 Dry as molded: All test values indicated herein are based on material and specimens with moisture content not exceeding 0.2% except where noted (Moisture Conditioned) (test according to ISO
9、 15512 Method B/ASTM D6869). All test materials have to be sealed in moisture proof containers and stored at 23 +/- 2 C for at least 24 h immediately after processing. If the moisture content exceeds 0.2% condition the material for a minimum of 16 h at 40 50 C at a reduced pressure below 133 kPa. Co
