To calculate the Melt Flow Rate:
\[ MFR = \frac{WE \times 600}{T} \]
Where:
The melt flow rate (MFR) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer that flows in ten minutes through a capillary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures.
Let's assume the following values:
Using the formula:
Step 1: Multiply the total weight of material extruded by 600:
\[ WE \times 600 = 50 \times 600 = 30000 \]
Step 2: Divide by the total time of extrusion:
\[ MFR = \frac{30000}{300} = 100 \text{ g/10-min} \]
Let's assume the following values:
Using the formula:
Step 1: Multiply the total weight of material extruded by 600:
\[ WE \times 600 = 75 \times 600 = 45000 \]
Step 2: Divide by the total time of extrusion:
\[ MFR = \frac{45000}{450} = 100 \text{ g/10-min} \]
