SCOPE The materials defined by this specification is a 30% sisal fiber filled injection thermoplastic molding compound based on 70% polypropylene copolymer prime 2. APPLICATION This specification was released ori
3、ginally for injection molding compound, color pigmented and with added UV-stabilization for exterior use 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-
4、A). 3.1.1 All requirements of this specification, identified by symbol (s), shall be met with data representing 3 sigma values. 3.2 SISAL FIBER The sisal fiber length must be at least 3.0 mm. The material must be dried for 5 h at 90 - 95 C minimum in a mechanical convection oven. The fiber humidity
5、before the extrusion of the polypropylene compound must be less than 3%. 3.2.1 Drying Process To achieve good results at the drying process sisal fiber (3%), we recommend 1) Forced Air Circulation oven with dry air line (The distances between the trays at the oven must be 5cm or more. The maximum he
6、ight allowed per tray is 5cm. To improve the efficiency of drying process is recommendable some small holes under the tray) Or 2) Continuous drier turbulent hot air flow/fluidized bed drier ENGINEERING MATERIAL SPECIFICATION WSS-M4D1002-A Copyright 2014, Ford Global Technologies, LLC Page 2 of 5 3.3
