GBPI GBB-R Melt Flow Index Testing Equipment flow rate ratio

Melt Flow Index Testing Equipment



Function and usage

To test the melt flow rate (MFR, unit: g/10min) of thermoplastic material in
high temperature, such as polyethylene, polystyrene, polypropylene, ABS
resin, acetal resin, polycarbonate, nylon, and fluoroplastic etc, widely
used in industries of plastic material, plastic products, petroleum,
chemicals, research institute, inspection agency and so on.



Standards:

GB/T9643, GB/T3682, JB/T5456, ISO1133



Working principle:
GBB-R Melt Flow Indexer makes the test material reach molten state at a
prescribed temperature in the high-temperature furnace. Such melt test
material goes through a small hole of specific diameter at a normative load,
subjected to extrusion test. In the production of plastics, MFI is usually
used to indicate the fluidity, viscosity and other physical properties of
polymers. Melt flow rate is expressed in the weight or volume of polymer per
10 minutes of the test or the average weight of each extruded material.



Applications:

Thermoplastic materials such as polyethylene, polystyrene, polypropylene,
ABS resin, polycarbonate, nylon, fluoroplastic and etc.
