ASTM D1238-98 Thermoplastics Melt Flow Index Tester , MVR / MFR Testing Equipment
ASTM D1238-98 Thermoplastics Materials Melt Flow Index Tester, MVR/MFR Testing Equipment designed for precise measurement of melt flow properties in thermoplastic materials.
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
