Techmer PM’s black pigment for plastics can be sorted by recycling systems that use near-infrared light to identify different materials.

NIR Black Techmer PM’s black pigment for plastics can be sorted by recycling systems that use near-infrared (NIR) light to identify different materials. This is in contrast to commonly used carbon black pigments that absorb NIR light, making it nearly impossible to sort plastics containing them.

What’s new? Improved grades of NIR Black colorant that work with HDPE, PP and PET and are FDA-compliant, allowing for use in food containers. Techmer can tailor the pigment to accommodate different resin grades, product thicknesses and the level of post-consumer content.

Benefits Improved recyclability for black plastics. The new grades facilitate recycling of black plastic products, allowing brand owners to better meet sustainability goals without compromising on color quality.
