SCOPE The material defined by this specification is a general purpose injection molding compound composed of a polypropylene matrix, with 40% by weight long glass fi
3、ber reinforcement with typical fiber length between 9-16 mm. 2. APPLICATION This specification was released originally for material used for bolsters. 2.1 LIMITATIONS This material does not contain UV stabilizers, long term exposure to direct sunlight will cause chalking and loss of gloss. 3. REQUIR
4、EMENTS 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). Note: Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which i
