The recycling of polymers is associated with many challenges. ColVisTec offers inline solutions for two important aspects: Automated color control and detection of impurity polymer content (contamination).

RecyColor is an automated color control system in combination with the inline UV/Vis spectrometer InSpectro X. The amount of pigment required to color the recyclate is automatically regulated to a target color value (one-dimensional). This is done using a specially developed algorithm that generates exact results with the aid of the residence time distribution and analysis with ReTA. It is irrelevant how large the color variations of the input material are. These differences are maintained very precisely, taking into account the saturation limits, so that a continuously consistent color quality is guaranteed.

RecyQuant is a precise tool for the continuous determination of impurity polymer contamination in recycling processes. This is done directly in the polymer melt using the InSpectro NIR near-infrared inline spectrometer. The foreign polymer is determined as a percentage of the main polymer in real time.
