The effect of zinc stearate on the processability of high density polyethylene (HDPE)

Polyethylene (PE) is one of the most widely used thermoplastics in the world, due to its good properties such as toughness, excellent chemical inertness, low friction coefficient and ease of processing, but the mechanical properties of polymers, including polyethylene, are influenced of molecular weight distribution. in this research, by adding 0.1% by weight of zinc stearate to high density polyethylene (HDPE) and The study of molecular weight distribution on the melt viscosity of the prepared samples was done using the flow rate ratio (FRR) test.
