Melt flow analysis
How easily a polymer flows at a set temperature and load, measured by extruding the sample through a heated capillary die. Processors use it to set extruder and molding parameters, tune compounding ratios, run quality control and detect polymer degradation.
- Reported as
- Melt flow rate, g/10 min
- Melt volume rate, cm³/10 min
