2、ERIOR, ANTI-SQUEAK 1. SCOPE The material defined by this specification is an enhanced anti-squeak performance based thermoplastic UV stabilized, medium impact molding compound based on a blend of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) for mold-in-color interior applications. 2.
3、 APPLICATION This specification was released originally for material used air register applications requiring anti-squeak performance and UV stability. 2.1 LIMITATIONS The use of HALS (Hindered Amine Light Stabilizers) is prohibited in PC+ABS materials. 3. REQUIREMENTS 3.1 APPROVED SOURCES This spec
4、ification 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 list of approved sources is located within Ford at or available externally through a For
5、d 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% relative humidity. Testing of the material should occur in the conditioning environment or soon
6、 after removal. 3.3 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS 3.3.1 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 specification minimum, maximum or range was establish
7、ed using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.3.2 This specification is based on virgin material and does not allow the addition of recycled content (PIR/PCR). 3.3.3 Performance Criteria: Parts using this specification shall meet the app
8、ropriate performance specifications: WSS-M15P4-G/Latest, for interior mold-in-color applications. Parts must fulfill applicable SDS/CDS requirements.
