NIR Black Masterbatch

Black and colored plastics place the highest demands on the separation of plastics recycling.
With the widespread NIR sensor technology, the near-infrared spectrum reflected by the plastic is evaluated. Each type of plastic has a characteristic spectrum and can be identified, sorted and finally recycled.

Up to now there has been a big problem with black and dark-colored plastics: the soot used for blackening in plastics absorbs a large part of the radiation both in the visible and in the infrared wavelength range. So far, it has not been possible to obtain a sufficient signal from black and dark-colored plastics and consequently these cannot be differentiated and sorted according to types of plastic.
