Melt Flow Indexers are afordable bnch top instruments that measure the melt mass-flow rate (MRF) and melt volume-flow rate(MVR) of wide range of thermoplastic raw materials(guanulate). Melt Flow Index Tester is manufactured as per ASTM D 1238 to measure the flow rates of thermoplastics by extrusion plastometer. This test indicates the Uniformity of the flow rate of the polymer.
