Product Description
ISO 1133 Melt Flow Index Tester MVR MFI MFR Plastic Equipment
Equipment Overview
The Plastic MFI Melt Flow Index Test Equipment is designed to determine the melt flow rate of thermoplastics (MFR; units: g/10min). This instrument is suitable for testing polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon, and various other polymer fluorides to determine their melt flow rate at high temperatures.

Working Principle
The Plastic MFI Melt Flow Index Test Equipment operates by melting the test material under specified temperature conditions using a high-temperature furnace. In the molten state, the material is extruded through a standardized diameter orifice under the force of applied weight loads. The melt flow rate represents the polymer material's fluidity and viscosity properties in the molten state, commonly used in industrial and research applications.
Melt Flow Rate Formula:
MFR (θ, mnom) = tref * m / t = 600 * m / t (g/10min)
Where:
θ - Test temperature
mnom - Nominal Load (Kg)
m - Average cut quality (g)
tref - Reference time (10min): 600
t - Cut-off time interval (seconds)
MFR (θ, mnom) = tref * m / t = 600 * m / t (g/10min)
Where:
θ - Test temperature
mnom - Nominal Load (Kg)
m - Average cut quality (g)
tref - Reference time (10min): 600
t - Cut-off time interval (seconds)
Calculation Example
Sample Data: Cut sections every 30 seconds: 0.081g, 0.086g, 0.081g, 0.089g, 0.082g
Calculation:
Average cut quality m = (0.081 + 0.086 + 0.081 + 0.089 + 0.082) ÷ 5 = 0.0838 ≈ 0.084g
MFR = 600 * 0.084 ÷ 30 = 1.680 g/10min
Calculation:
Average cut quality m = (0.081 + 0.086 + 0.081 + 0.089 + 0.082) ÷ 5 = 0.0838 ≈ 0.084g
MFR = 600 * 0.084 ÷ 30 = 1.680 g/10min
Applications
This equipment is essential for factories, manufacturing enterprises, and research institutes involved in plastic production, quality control, and material research.
