About Melt Flow Testing ASTM D1238

Melt flow testing is simply a measure of the flow of a polymer when melted. The result of a melt flow test, called the melt mass-flow rate (MFR) or melt volume-flow rate (MVR), is defined as the amount of mass or volume of a polymer that flows through a small die at a specified temperature and pressure. It is often used in the plastic industry for quality control of thermoplastics.

The melt flow test itself is straightforward. The method is described in the standards ASTM D1238 and ISO 1133. A small sample of about 5 grams is heated above its melting or softening point and forced to flow through a capillary using a piston actuated by a specified weight, usually 2.16 kg or 5 kg. The weight of melt in grams flowing through the capillary in 10 minutes is the melt flow index.
