Product Description
Plastic Melt Index Testing Machine(GW-082B) 
Product Description
Plastic Melt Index Testing Machine

Equipment Description:
The Melt Flow Index MFI Test Equipment is used for the determination of thermoplastic melt flow rate (the
MFR; Units: G/10min) instrument. For polyethylene, polypropylene, polyoxymethylene, ABS resin,
Polycarbonate, nylon fluorine plastics and other polymer melt flow rate determination at high temperatures.

How It Works:
The melt flow rate instrument under specified temperature conditions, the analyte to reach the molten state, with a
High temperature furnace. The molten state of the measured object, the gravity of the weight load of the provisions
Of a certain diameter of the hole extrusion test. Often used in plastic production of industrial enterprises and
Scientific research units, the melt flow rate (quality) "to represent the fluidity, viscosity and other physical properties
Of polymer materials in the molten state. The melt flow rate means out of the average quality of the segment sample
Of the material is converted into the extrusion of 10 minutes. Melt (mass) flow rate of said MFR, unit: G / 10 minutes (ie, g / min)
Formula: MFR (θ , mnom) = tref × M / t = 600 * m / t (g/10min)
Where: θ - Test temperature
Mnom - nominal load Kg
M - the average quality of the cut g
Tref - reference time (10 min): 600
T - the cut off time interval unit: Seconds.
Example: A group of plastic sample every 30 seconds cut for some, the quality of the results of each segment
Is: 0.081 g, 0.086 g, 0.081 g, 0.089 g, 0.082 g.
Cut off the average mass m = (0.081 +0.086 +0.081 +0.089 +0.082) ÷ 5 = 0.0838 0.084 (g)
Into the formula: The MFR = 600 * 0.084/30 = 1.680 (g / 10 minutes)

By Industry:
Applicable to the production of factories and enterprises and scientific research units and research.

Meet the Standards:
The machine in accordance with the the GB/T3682-2000 requirements of design and manufacture
