Filtratest
Analysis of polymer impurities
The Filtratest is used for the exact determination of the foreign substance concentration and quality-reducing inhomogeneities. The procedure is suitable for the description of concen-tration, size of particles, kind of foreign substances, and higher-viscous particles regarding the test material. The quality of the extrudate is described with regard to concentration, particle size, kind of foreign substance, and higher-viscous particles in the melt.
The melt flows through finely woven sieves. Due to the deposit of the foreign substances the pressure increases. It is measured by means of a pressure transducer in front of the insert and recorded continuously during measurement. The additional analysis of the deposit gives more information about kind and amount of polymer impurities.
