2、ZED, 10% GLASS REINFORCED WSS-M4D1011-A1 BLOW MOLDING COMPOUND 1. SCOPE The material defined by this specification is a thermoplastic 10% glass fiber reinforced, heat stabilized, blow molding compound based on polyamide 6. 2. APPLICATION This specification was released originally for material used f

3、or low pressure turbo duct applications. 2.1 LIMITATIONS 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 U

4、V stabilizers, long term exposure to direct sunlight 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 150 C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FO

5、R 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 mean and +/- 3 si

6、gma 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, however materi

7、als with recycled content as defined by WRS-M99P42-A1 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever feasible. The use of regrind is permitted, for economic and environmental reasons, with compliance as indicated in WSS-M99P1111-A. 3.1.

8、2 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 15512 Method B/ASTM D 6869).
