The filling of our extrusion plants is exclusively done by high-tech dosing differential scales - both for solids and liquids.
In addition to the evaluated permanent process control via pressure and temperature sensors, we have decided to use the highly innovative inline spectroscopy system of ColVisTec AG.
The inline spectroscopy process control enables us to detect the smallest material variations already in the melt and to correct the process "just in time".
The melt index test is carried out according to the standards of ISO 1133 and ASTM D1238.
Other test methods are of course available on request.
