The Melt Index Tester (Melt Flow Rate Meter) is a precision instrument for evaluating the flow properties of thermoplastic materials under specified conditions. By automatically extruding polymer melts through a standardized die and measuring the mass or volume flow, it determines the Melt Flow Rate (MFR), providing critical information on polymer processability, molecular weight, and quality control. The instrument supports both manual and automated testing, with accurate temperature control and built-in data output.
Standards
(1) ISO 1133 – Plastics – Determination of the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastics.
(2) ASTM D1238 – Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer.
(3) GB/T 3682 – Plastics – Determination of the melt flow rate (MFR).
(4) JIS K7210 – Japanese Industrial Standard for measurement of thermoplastic melt index.
(5) Additional industry-relevant ISO and ASTM standards for polymer characterization and processability assessment.
Features
(1) Rapid heating with minimal temperature overshoot for consistent test conditions.
(2) High-accuracy PID temperature control (±0.1°C) with over-temperature protection.
(3) Automatic recovery to constant temperature after sample loading.
(4) Supports both manual and automatic cutting methods for test sample extrusion.
(5) Built-in Chinese LCD display with intuitive interface.
(6) Integrated printer for automatic result output.
(7) Reliable, stable operation with precise, repeatable measurements.
