Adjusting Variables to Optimize the Melt Flow Index

Pacorr Melt flow index tester is a lab testing equipment to measure the flow ability of the thermoses used worldwide in polymer based manufacturing industries. We rigorously work on the factors affecting melt flow index while designing this tester to make the obtained data more reliable and highly precised.

To know the details regarding its working you can read the role of melt flow ratio index in polymers.

Why is MFI so crucial to evaluate? We need to understand this, as we know that to perform various types of molding, thermoforming and extrusion, deep insight into the flow characteristic of polymers is very important.

In this blog we focus on the important key factors which will definitely guide the researchers and the manufacturer to acquire accurate and precise results by avoiding the rejection of lots and make your polymer mass production highly productive.

Let’s discuss factors affecting melt flow index are as follows:

• Pressure is the load applied through the piston that passes through the heating barrel to the capillary die affects the viscosity of the molten polymers. The precise setting of pressure will not only obtain optimized processing conditions but also provide consistent and accurate MFI.
• Temperature change directly affects the density, velocity and viscosity of fluid polymers. So the characteristics of the flow changes as there is variation in temperature maintained in the heating barrel. Thus by maintaining the controlled supply of heat to the barrel will lead to the precise measuring of MFI.
• Sample selection process, uniform size of granules of polymers should be selected. The sample should not contain any air trap and impurity inside it because it can result in inconsistent flow and give error in MFI value. The proper sample preparation will avoid such issues and lead to more accurate MFI.

These are very important key factors which need to be carefully done during the experimentation of melt flow index testing. The accurately recognizing the MFI will lead to determine various other properties of polymers like Molecular weight distribution, viscosity, flowability characteristic, appropriate material selection and process applicability. Therefore improper MFI van can affect and enhance the quality and reliability of the polymer. So the Pacorr Melt Flow Index Tester strictly adheres to standardized international and industrial guidelines like ASTM 1238 and ISO 1133.
