Melt Flow Index - MFR Model

Model : MFI-MFR

The Melt Flow Index – MFR Model is a high-precision polymer testing instrument engineered to measure the melt flow rate (MFR) of thermoplastic materials with exceptional accuracy and consistency. Ideal for laboratories, plastic manufacturing units, and research facilities, this advanced testing machine evaluates how a polymer melts and flows under controlled temperature and pressure conditions. Built in compliance with ASTM D1238 and ISO 1133 standards.

What is the Melt Flow Index – MFR Model?

The Melt Flow Index (MFR) Model is a precision testing instrument designed to measure the melt flow rate of thermoplastic polymers. It determines how easily a polymer melts and flows under specific temperature and pressure conditions. The MFR value helps manufacturers understand the viscosity, molecular weight, and processing characteristics of plastics. Built for accuracy and consistency, the Melt Flow Index – MFR Model ensures reliable results for both quality control and research laboratories in the plastics industry.

How Does Melt Flow Index – MFR Model Work?

The MFR Model works by extruding a small amount of molten polymer through a standard die under controlled temperature and load. The amount of material that flows in 10 minutes is measured as the Melt Flow Rate (g/10 min).

This process is governed by international testing standards such as ASTM D1238 and ISO 1133. The instrument is equipped with a digital temperature controller, precision piston, and automated timing system for consistent test conditions. The result provides critical data for evaluating processability, quality, and material performance in production.
