2、ONTENT 1. SCOPE The materials defined by this specification is a mineral reinforced, heat stabilized polyamide 66 molding compound containing 25% post consumer re-cyclate. 2. APPLICATIONS This specification was released originally for material used for climate control blend doors. This material shou

3、ld be used when a dimensionally stable, chemically resistant, black engineering polymer is required. 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 se

4、rvice/assembly environment. This material is manufactured using post consumer nylon, it should not be used in applications requiring color mastering. This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of properties. 3. REQUIREMENTS 3.1 S

5、TANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 All requirements of this specification, identified by symbol (s), shall be met with data representing 3 sigma values

6、 using latest ISO test methods. 3.1.2 This specification is based on virgin material only. The use of in-house regrind is not allowed unless the part is validated during PV testing with the documented level of regrind noted on the part drawing. 3.2 MOLDING COMPOUND (s) 3.2.1 Melt Temperature 249 256

7、 C (ISO 3146 2ndHeat) The material shall be dried for 2 h minimum at 80C in a mechanical convection oven immediately preceding the test.
