Polypropylene (PP)

Polypropylene is a relatively easy materials to injection mould in spite of its semicrystalline nature The absence of any real need for high molecular weight from the mechanical properties view point leads to low melt viscosity (easy flow) The pseudoplastic nature of polypropylene enhances this effect at high shear rates (fast filling rates)
