Melt Flow Index Testing Equipment
Function and usage
To test the melt flow rate (MFR, eenheid: g / 10min) van thermoplastisch materiaal in op hoge temperatuur, zoals polyethyleen, polystyreen, polypropyleen, ABS hars, acetaal hars, polycarbonaat, nylon-, en fluoroplastische enz, veel gebruikt in industrieën van plastic materiaal, plastic producten, aardolie, Chemicaliën, onderzoeksinstituut, inspectiebureau enzovoort.
normen:
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.
toepassingen:
Thermoplastic materials such as polyethylene, polystyreen, polypropyleen, ABS hars, polycarbonaat, nylon-, fluoroplastic and etc.
