SCOPE The material defined by this specification is a heat stabilized polyamide 66 molding compound. 2. APPLICATION WSS-M4D648-B1 material is being released non-visible applications. WSS-M4D

3、648-B2 material is being released for molded in color interior 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 environme

4、nt. B1 suffix only: This material typically does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss without suitable additives. This material is not suitable for long term exposure to engine coolant, or direct exposure to strong acids or bases. It

5、 is not suitable for use above 155 C. 3. REQUIREMENTS 3.1 STANDARD 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 Note: Many 4D resin specifications prior to 2011, identif
