HEXA PLAST provides Melt Flow Indexer with customized controller keeping in mind the process of test.
Precise Temperature with accuracy of + 0.1º C.
Microprocessor based digital timer with facility to select number of test, cutter time, buzzer indication on completion of test and advance buzzer indication for manual cutting procedure.
Fully Automatic MFI is having facility to conduct to test independently by pre-setting the temp. of test, time & applying the required Load and it will directly give the result of MFI for individual test & average of all test.
Determination of melt flow index of thermo plastic materials
Definition: Melt flow index is defined as the rate of extrusion of molten resin under specified temperature and pressure through a specified size of die in 10 minutes. It is expressed in g/10 min.
MFI Tester capable of maintaining tem. From ambient to 350°C
Principle & Significance: This characteristic is primarily useful for measuring uniformity of flow rate of materials. This is used for grading of Thermoplastic material and their quality control i.e. in determining lot-to-lot consistency of resin. A material having high molecular weight has more resistance flow than the flow molecular weight polymer.
