Analysis of polymer impurities

The Filtratest is used to check the purity and accurately determine foreign particle concentrations in spinnable polymers (e.g. PET, PA) and other thermoplastic melts.

The melt flows through a fine-meshed filter disc, in which the foreign particles are gradually deposited. The deposited dirt particles increase the pressure, which is measured by transducers and recorded during the measurement.

Subsequent analysis of the sieves allows indications of the type and quantity of polymer contamination.
