A. Schulman HPP35GS01BK 35% Talc Fiberglass/Mica Reinforced, Chemically-Coupled, Heat-Stabilized, Impact-Modified Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP); Polypropylene, Glass/Mineral Reinforced

Material Notes: 35% Talc Fiberglass/Mica Reinforced, Chemically-Coupled, Heat-Stabilized, Impact-Modified Polypropylene

Description:

Applications: Primary use is for rear quarter wheel opening shields

Specifications: Meets/exceeds Ford Engineering Material Specification ESB-M4D640-A.

Comments:
Tensile/Izod Change (1000 hrs./140°C): +8/-3%; ESB-M4D640-A Specification: ±15/-15; ISO 188
Filler Content: 34.5 %; WSB-M4D640-A Specification: 33.0-37.0; 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- 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.
