This test, being the most common test for plastics, is used to measure and determine the flow rate of the material.
A Guide to Polyolefin Film Extrusion - LyondellBasell
www.lyondellbasell.comMelt index (MI) is inversely related to the resin’s average molecular weight: as average molecular weight increases, MI decreases. Generally, a polyolefin resin with high molecular weight has a low MI, and vice versa. Melt viscosity is an extremely important property since it affects the flow of the molten polymer. The resin’s flow when
