A. Schulman Gapex® FPP30GQ03HB 30% Fiberglass/Mineral Reinforced, Chemically-Coupled, Impact-Modified Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Glass/Mineral Reinforced

Material Notes: 30% Fiberglass/Mineral Reinforced, Chemically-Coupled, Impact-Modified Polypropylene

Description: Tan

Testing and measurements were performed at 73 ± 3°F and 50± 5% relative humidity unless otherwise noted.
Filler Content: 30.5%; ASTM D2584
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- Weigh pars for consistent packing. Cushion (Range): 0.2-0.5 in. Nozzle Type: Free flowing/Standard.
Some conditions may have to be altered to obtain acceptable parts. back pressure must be minimized to retain fiber length and optimize performance. Please do not run too cold, molded in stress & rough surface may become a problem. If you must run below melt or temperature recommended for dimensional precision you may compromise impact and esthetics. Retest parts to confirm performance.
