Supplied byAdvanced Composites (Mitsui Chemicals)- Last Updated on Mar 23, 2021
BJ4H-G by Advanced Composites (Mitsui Chemicals) is high impact and flow polypropylene (PP) grade. It is designed for injection molding method. BJ4H-G is recommended for manufacturing of interior parts. During processing, holding pressure should be lower than boost pressure with a minimum amount of time to prevent over-packing of the part and screw should stop 1 to 2 seconds before mold open. Lower RPM of screw is preferred for mixing and uniform melt temperature. Injection speed should be slow to medium to prevent excessive shear on the material.
