The test method includes determining the rate of extrusion of molten thermoplastic resins with the help of an extrusion plastomer. Once preheated at a specified, resin is extruded through a die with a specified length and orifice diameter under prescribed conditions of temperature, load, and piston position of the barrel. There are several procedures used in ASTMD1238standardtestmethod:
Procedure A determines the meltflowrate (MFR) of a thermoplastic material, measure in grams of material/10 minutes (g/10 min). The method is based on the measurement of the mass of material extruding from the die over a given period of time. The procedure is applicable for materials with melt flow rates between 0.15 and 50 g/10 min.
Procedure B determines the MFT and melt flow volume rate of thermoplastic materials and is used for materials that have flow rate from 0.50 to 1500 g/10 min.
Procedure C determines the MFT of polyolefin materials and is also used an alternative to procedure B that has melt flow rate more than 75 g/10 min. This method uses modified die (referred to as a half-die).
Procedure D is referred as “Flow Rate Ratio” (FRR) test that determines MFR using two or three different test loads (either increasing or decreasing the load during the test) on one charge of material.
Melt Flow Index Tester Complied with ASTM D1238 Standard Test Method
Presto’s MeltFlowIndexTester evaluated the flow properties of the molten plastics or resins and defined as the rate of flow (in grams per 10 minutes) of extrudates of molten resins through a jet of a specific length and diameter. The test is performed under suggested conditions of load, temperature and piston position in a cylindrical cavity inside a heated metallic tube barrel.
