Objectives:
- To determine the melt mass flow rate MFR of thermoplastics materials under specified conditions of temperature and load.
- Compare between raw and manufactured material in MFR.
Introduction:
One of materials’ properties is the melt mass flow rate which describes the viscosity of the polymer in the melt phase. . It is defined as the mass of polymer in grams flowing per 10 minutes through a capillary of specific diameter and length by a pressure applied via a range of standard weights at specified temperature.
