The Melt Flow Index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures. Polymer processors usually correlate the value of MFI with the … Webviscosity is push over flow, its inverse, melt index, is flow over push, or the amount of flow for a given amount of push, and a low melt index means a resin that flows with more …
