Applications

This Plastic Melt Flow Index Test Instrument complies with GB/T3682-2000 and ASTM D1238-98 standards, with reference to JB/T5456 and ISO 1133. It is used to determine the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastics materials.

Automatic sampling method with balance weighing for MFR determination
Displacement transducer and auto timer system for MVR measurement
Results displayed on LCD screen with printing and computer export capabilities
Suitable for high melt temperature engineering plastics (PC, FI plastics, nylon)
Compatible with lower melt temperature plastics (PE, PP, POM, PS, ABS resin, poly carbonic acid ester)
Wide applications in plastic fabrication, petrochemical industry, research institutes, and quality inspection departments
