1. Product Overview
The Melt Flow Index Tester is designed in accordance with ISO 1133 and ASTM D1238 for the determination of melt mass-flow rate (MFR) of thermoplastic materials. The instrument measures melt flow rate using an automatic sampling and weighing method, and calculates the final melt flow index based on standard formulas. Test results are displayed on the LCD screen and can be printed via the built-in micro-printer.
The tester provides stable temperature control, accurate load application, and reliable measurement performance. It is suitable for testing engineering plastics and general-purpose plastics with relatively low melting temperatures.
2. Application
The instrument is used for melt flow rate testing of thermoplastic materials, including but not limited to:
Polyethylene (PE)
Polypropylene (PP)
Polyacetal (POM)
Polystyrene (PS)
ABS resin
Polycarbonate (PC)
Nylon (PA)
Fluoroplastics
3. Standards
The Melt Flow Index Tester complies with the following standards:
ISO 1133 — Plastics — Determination of the Melt Mass-Flow Rate (MFR) and Melt Volume-Flow Rate (MVR)
ASTM D1238 — Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer
