Plastic Melt Flow Indexer Plastic Melting Point Tester
Liyi melt flow index extrusion plastometer applies to both molten high temperature of the PE, gather fang PSF, fluorine plastic, nylon engineering plastic, also suitable for polyethylene, polypropylene polystyrene, ABS resin, pom resins melting temperature lower plastic tests.
Meet the standards:
ASTM D 1238, ISO1133, GB/T3682
Characteristic:
1. Liyi melt flow index extrusion plastometer using advanced electronic measurement technology, liquid crystal display test results, the micro printer output results and calculating the quality of the melt flow rate (MFR) or melt volume flow rate (MVR) (note: single determination value and many times the average of the cutting material).
2. Tester compact structure, beautiful, the control system can real time measurement and display temperature numerical, has the upper limit temperature protection, constant temperature sound reminders, response time tip etc. Function. The use of advanced PID control technology and high speed and high resolution sampling circuit, make the machine in constant temperature is the following characteristics:
A: heating speed, the dinky overshoot.
B: constant temperature and high precision.
C: in the packing after, can quickly restored constant temperature condition.

New desigh of Liyi melt flow index extrusion plastometer:
How it works:
Melt flow rate meter is in the specified temperature conditions, with high-temperature furnace to melt the state of the measured object. The molten state of the measured object, the required weight load by gravity out of a certain diameter hole in the test. Plastics in industrial enterprises and scientific research units of production, often with "melt (mass) flow rate" to represent the polymer material in the molten state of fluidity, viscosity and other physical properties. Melt flow rate refers to the extrudate, the average quality of the sample paragraphs are translated into 10 minutes of extrusion volume. Melt (mass) flow rate expressed by MFR, unit: g / 10 minutes (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 cut g
tref - reference time (10min): 600
t - cut off time interval unit: seconds.
Example:
A set of plastic samples, a cut every 30 seconds, the quality of the results section: 0.081 g, 0.086 g, 0.081 grams, 0.089 grams, 0.082 grams.
Cut the average quality m = (0.081 +0.086 +0.081 +0.089 +0.082) ÷ 5 = 0.0838 ≈ 0.084 (g)
Into the formula: MFR = 600 × 0.084/30 = 1.680 (g / 10 min)
