Melt Flow Testing

Melt flow testing expertise

Really handy if you’re working with polymers, melt flow testing is a way to predict how your resins will behave in their intended molding process. Save yourself time and money by investing in testing solutions that give you the information you need to get your products right.

Measuring your melt flow index

Melt flow index testing allows you to work out the overall quality, melt flow rate, capability and molecular weight of a resin material – factors that are an important aspect of polymer performance. Not sure why your melt flow index is so important? Our complete guide to melt flow indexing has everything you need to know,

Discover your melt flow rate

Our melt flow index testers are designed for simple and precise measuring of the Melt Flow Rate (MFR), also known as Melt Flow Index (MFI) and calculating the Melt Volume Rate (MVR) and pendulum impact.

Testing machines like the MFR300 Microprocessor Melt Flow System are easy to use and feature the latest on-board microprocessor technology, for extremely accurate results.

Compliance with melt flow index testing

Our ASTM and ISO compliant systems range from devices that perform simple manual tests through to semi-automated machines that can deliver multiple weight tests. We know how important it is to make sure you’re able to test to the standards demanded by your industry, that’s why we create solutions designed to fulfil the most important criteria.

Find melt flow testing devices that are compliant with  ASTM D1238,  ISO 1133 and more.
