2、MPOUND, INTERIOR WSS-M4D960-A2 1. SCOPE The material defined by this specification is a molded in color molding compound based on acrylo-nitrile-butadiene-styrene (ABS) and PA6 blend that has been UV stabilized for unpainted interior applications. It has excellent chemical and stress crack resistanc

3、e, high impact strength and low gloss. 2. APPLICATION This specification was released originally for material used for door switch bezels on the Crown Victoria/Grand Marquis platform to replace painted PC/ABS. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances mus

7、th compliance as indicated in WSS-M99P1111-A. 3.1.3 WSS-M99P1111-A exception for conditioning of PA. 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 15512ASTM

8、 D 6869). All test materials have to be sealed in moisture-proof containers and stored at 23 +/-2 oC for at least 24 h immediately after processing. If the moisture content exceeds 0.2%, conditioning the material for a minimum of 16 h at 40 50 oC at a reduced pressure below 133 kPa. Conduct tests in

9、 a controlled atmosphere of 23 +/- 2 oC and 50 +/- 5% relative humidity. Individual specimens shall not be removed from closed containers until immediately before testing.
