Soreide, NA Controlled document at www.MATS Copyright 2013, Ford Global Technologies, LLC Page 1 of 7 ACRYLONITRILE BUTADIENE STYRENE (ABS), WSS-M4D690-B1 MOLDING COMPOUND, HIGH HEAT RESISTANT, INTERIOR 1. SCOPE
2、The material defined by this specification is a molded-in-color, low gloss, high heat resistant molding compound based on acrylonitrile butadiene styrene (ABS) that has been UV stabilized for unpainted interior applications. High heat resistant ABS is defined as must having a mean Vicat Softening Te
3、mperature range from 103 C to 108 C. 2. APPLICATION This specification was released originally for material used for unpainted interior trim parts and non-visible brackets that require high heat capability. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and par
4、t 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 specification
5、 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. 3.1.2 This specification is based on virgin materials; however, materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post in
6、dustrial 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. 3.1.4 Materials used in interior applic
7、ations must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Component and Allergen Requirements. Data must be included in material submission package. 3.1.5 Performance Criteria: Parts using this specification shall meet the appropriate per
8、formance specifications: All mold-in-color components using this material must comply with all the requirements of WSS-M15P4-F/Latest for interior applications. 3.1.6 As specified in WSS-M99P1111-A, paragraph 3.2, Ford Materials Engineering may request a Control Plan and Certificate of Analysis (CoA
