Compliance With International Standards:

ASTM D1238
IS 2530 – Method A

Applications:

Melt Flow Indexer is used to measure the flow rate of different polymers. The reported Melt Index values help to distinguish between different grades of polymers. This is due to the fact that plastic materials are seldom manufactured without incorporating additives, which affect the processing characteristics of material like stability and flow ability.
The Melt Flow Index Test measures the rate of extrusion of a thermoplastic material through an orifice of specific length and diameter under prescribed conditions of temperature and pressure.
