Among the first instruments plastics moulders, extruders, and compounders are likely to consider when outfitting a new lab is a Melt Flow Indexer or “Melt Indexer.” Known as an extrusion plastometer in more technical jargon, this apparatus has long been used to determine the melt flow rate or mass flow rate (MFR) of virgin and compounded thermoplastic resins. With the increased pressure on plastics processors to comply with quality standards for quality management, more of them are using these instruments to evaluate incoming material and test finished products. The melt indexer consists of a heated barrel and piston assembly to contain a sample of resin. A specified load (weight) is applied to the piston, and the melted polymer is extruded through a capillary die of specific dimensions. The mass of resin, in grams, that is extruded in 10 minutes equals the MFR, expressed in units of g/10 min. (This value is also commonly called the melt index, MI, or melt flow index, MFI.) Some instruments can also calculate the shear rate, shear stress, and viscosity in centipoise.
