Demonstrated here is the proper method of starting and shutting down your LMI5500 melt flow indexer to maintain ideal operating conditions.

Melt Flow Testing Article Part 1

Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.

Melt Flow Testing Article Part 2

To fully appreciate the strengths and weaknesses of the melt-flow-rate (MFR) test it is important to know something about the way the test is performed.

Melt Flow Testing Article Part 3

There is a well-established relationship between something called the weight average molecular weight of a polymer and a parameter known as the zero-shear viscosity.

Melt Flow Testing Article Part 4

Few molders perform the test in-house. Of those that do, most don’t understand why they are doing it or what they are measuring.

Melt Flow Testing Article Part 5

There are two points in the manufacturing supply chain where a determination of average molecular weight (MW) is important. The first is when the material is first received by the molder. The second is after molding.

Melt Flow Testing Article Part 6

Once degradation has been established, the discussion inevitably turns to how it happened. It might be expected that the answer to this question is widely known. Not so. The good news is that the influences that cause polymer degradation during processing are few.

Melt Flow Testing Article Part 7

Here is why the melt flow test is not universal. As useful as the melt flow rate (MFR) test can be, it is not universally applicable. Fundamentally, the test is intended to document differences in molecular weight.

Melt Flow Testing Article Part 8

Here are the steps to take in cases where the MFR is not provided by the polymer supplier. The number of commercial materials that employ a melt flow rate (MFR) value as part of the published property profile attests tO the usefulness of the test.

Melt Flow Testing Article Part 9

Understanding the value of melt-volume rate. If you spend a lot of time looking at data sheets you have probably noticed a trend over the last several years in how the melt flow rate (MFR) is reported. Along with, or instead of, the MFR, a new line item is appearing called the melt volume rate (MVR).
