The AUTO GBR-D1 Melt Flow Index Tester is a precision testing instrument for packaging materials, aligning with ISO, GB, and other international standards to meet market demands. It is designed for measuring the thermoplastic melt mass flow rate (MFR) and melt volume flow rate (MVR).
Test Principle Under specified temperature and load conditions, the melt mass flow rate (MFR) and melt volume flow rate (MVR) are calculated from the molten material extruded through a die of specified length and diameter.
Standards GB/T 9643, GB/T 3682, JB/T 5456, ISO 1133
