A. Schulman Gapex® RPP30EB56BK 30% Fiberglass Reinforced, Chemically-Coupled, Heat Stabilized, Homopolymer Polypropylene containing 25% minimum P.C.R.
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene with 30% Glass Fiber Filler
Material Notes:	30% Fiberglass Reinforced, Chemically-Coupled, Heat Stabilized, Homopolymer Polypropylene containing 25% minimum P.C.R. Description: Precolored black Applications: Primary use is for battery tray supports. Specifications: Meets/exceeds Ford Engineering Material Specification WSS-M4D732-A5 Comments: Tensile/Izod Change (1000 hrs./140°C): +7/-12%; WSS-M4D732-A5 Specification: ±25/-25; ISO 188 Filler Content: 30.3% ;WSS-M4D732-A5 Specification: 28.0-32.0; ISO 3451/1A Material Pre-dry: Normally it is not necessary to pre-dry this material. However, if conditions dictate drying to optimize material properties and part appearance then dry in a desiccant dryer at 180°F for 2-3 hours or 160°F for >4 hours. Manifolds: Maintain manifolds, runners and tips 10 to 20°F above the front one temperature to allow easier filling. (Gate drool is best eliminated using screw decompression rather than reducing tip temperature.) Back Pressure (Range): 20-50 psi. Injection Speed: medium to slow > depending on surface appearance. Screw Speed: medium. Injection Pressure: Adjust to just above a short shot. Injection Time: Adjust to just above a short shot. Cushion (Range): 0.2-0.5 in. Nozzle Type: Free flowing/Standard. Some conditions may have to be altered to obtain acceptable parts. Please do not run too cold, molded in stress and rough surface may become a problem. If you must run below melt or temperatures recommended for dimensional precision you may compromise impact and esthetics. Retest parts to confirm performance.
