In an industry striving to achieve a circular economy, ELIX Polymers has taken a decisive step forwards with an innovative solution that addresses one of the major challenges in recycling technical plastics: the identification of black materials during sorting processes. The company is now introducing its new colours based on NIR-detectable deep black pigments for ABS and PC/ABS, a breakthrough that combines premium aesthetics, thermal performance and recyclability, supporting global sustainability goals.

For years, carbon black pigments have been the preferred choice for applications requiring a sleek and sophisticated finish. However, these pigments block the signal of near-infrared (NIR) optical sorting systems, making black plastics invisible to recycling plants. This limitation has posed a challenge for the entire value chain – from manufacturers to recyclers and brands – seeking solutions to reduce waste and comply with increasingly stringent sustainability regulations.

Recognising this issue, ELIX Polymers has developed a range of ABS and PC/ABS materials in a deep black colour that can be detected by NIR, Raman, and hyperspectral imaging (HSI) technologies. This innovation ensures that products made with these materials can be efficiently identified and recycled without compromising the aesthetics or mechanical properties that define engineering plastics. Additionally, the solution incorporates the “Cool Colour” effect, which significantly reduces surface temperature under sunlight exposure, improving thermal comfort in outdoor applications.

The impact of this development goes beyond technical improvement. It represents a strategic advancement for the industry, which no longer has to choose between design and sustainability. With this technology, manufacturers can deliver attractive, functional products that, at the end of their life cycle, can be integrated into more efficient recycling processes, reducing waste and optimising resource use. This innovation aligns with global commitments to lower carbon footprints and accelerate the transition to a circular economy where every material has a second life.

“At ELIX Polymers, we believe innovation must go hand in hand with responsibility. Our goal is to lead the transition towards materials that combine design, functionality and recyclability. This technology proves that aesthetics and sustainability can coexist”, states Pedro Urbaneja, Colour Technician from the R&D team.

This launch reinforces ELIX Polymers’ position as a strategic partner for customers seeking advanced solutions in technical polymers. The company continues to work on projects that address recyclability challenges across the entire supply chain, developing materials that facilitate sorting and reuse of plastic waste. With initiatives like this, ELIX Polymers consolidates its role as a benchmark in the transformation towards a more responsible and environmentally-committed industry.
