2、ENT WSS-M4D741-B1 RESISTANT MOLDING COMPOUND 1. SCOPE The material defined by this specification is a thermoplastic injection molding compound based on polypropylene homopolymer. This material is resistant to engine coolant. 2. APPLICATION This specification was released originally for material used

3、 for overflow/degas bottles. 2.1 LIMITATIONS This material has low impact 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 STANDARD R

4、EQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). Note: Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mea

5、n and +/- 3 sigma values were to be reported. The specification 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. 3.1.1 This specification is based on virgin materials,

6、 however materials with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible and following all materials and PV testing required by Ford Materials Engineering. The use of regri

7、nd is permitted, for economic / environmental reasons, with compliance as indicated in WSS-M99P1111-A. 3.2 SAMPLE PREPARATION 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 conditio
