Today, plastic waste is sorted using automatic optical sorting methods. Most sorting machines are based on the reflection of NIR wavelengths. Carbon black absorbs infrared light, making identification via optical sensors impossible. The result is that non-detectable black or dark plastics end up in landfills or are incinerated.
W&R understands this issue and as a result has developed various alternatives. We have introduced NIR-detectable and sortable colour masterbatch solutions. By using specific pigment formulations, NIR-detectable masterbatches are created. This makes your end product suitable for the correct recycling and sorting methods.
Â
We have an existing range of NIR-detectable masterbatches available from stock. These include the most common colours in various shades such as gray, terracotta, brown, taupe, blue, and green.
Â
We can also provide the most effective solution for your specific requirements. With our range of NIR-detectable masterbatches, we have taken a big step forward in one of our core values: improving ecological sustainability and circularity.
Â
Good to know: our NIR-detectable black masterbatches (which obviously do not contain Carbon black) are available and suitable for various polymers such as PE, PP, PS, and PET.
Our perception of the world around us is predominantly inspired by colour. Today, we are using more and more plastic materials in an increasing number of products and in as many different colours. In addition to our broad range of products, we develop masterbatches to meet the precise requirements of our clients application.Â
Acting on fast changes in customer needs, manufacturers want to be able to anticipate when it comes to the raw materials they purchase and use for design, colour and additional properties in this dynamic industry.
