Cabot Corp., a global manufacturer of black masterbatch, launched its new REPLASBLAK product family of circular black masterbatches with certified material. Black masterbatch is a combination of black carbon pigment, resin, and other additives in granular form used to color plastics.

Three new products will be sold as the company’s first International Sustainability & Carbon Certification (ISCC Plus) certified black masterbatch products powered by Evolve Sustainable Solutions. Cabot’s recently launched Evolve Sustainable Solutions platform delivers products with sustainable content and reliable performance at an industrial scale across three categories — recovered, renewable, and reduced, said Cabot.

Masterbatch suitable for packaging, automotive applications

Increased environmental pressure is driving greater demand for black masterbatch products that support a circular economy and decrease greenhouse gas (GHG) emissions, the company said. The new products can be used in various applications in the automotive, agriculture, packaging, and building and construction segments. 

Cabot’s three new black masterbatch products powered by Evolve Sustainable Solutions under the recovered category include the following:

  • REPLASBLAK rePE5475 100% circular black masterbatch leverages 100% ISCC Plus mass balance–certified material made from reclaimed carbon from end-of-life tire pyrolysis and mechanically recycled polyethylene. GHG emissions are reduced by more than 60% compared with standard black masterbatch and the material adheres to the ISCC Plus voluntary add-on GHG emission requirements, the company said. It supports medium tint strength, making the material suitable for compounding, recycling, injection molding, and sheet extrusion applications relevant to the automotive, agriculture, packaging, and building and construction segments.

  • REPLASBLAK rePE5265 70% circular black masterbatch leverages 70% ISCC Plus mass balance–certified material made from mechanically recycled polyethylene. It reduces GHG emissions by nearly 50% in comparison to standard black masterbatch and adheres to the ISCC Plus voluntary add-on GHG emission requirements, the company said. It delivers high gloss and jet pigmentation in thermoplastics, making it suitable for compounding, recycling, injection molding, and sheet extrusion applications in the automotive segment.

  • REPLASBLAK rePE5250 60% circular black masterbatch leverages 60% ISCC Plus mass balance–certified material made from mechanically recycled polyethylene. It reduces GHG emissions by nearly 50% in comparison to standard black masterbatch and adheres to the ISCC Plus voluntary add-on GHG emission requirements, the company said. It delivers high tint strength making it suitable for compounding, recycling, injection molding, and sheet extrusion applications relevant to the automotive segment. 

ISCC is a globally applicable certification system designed to ensure compliance with ecological and social requirements, GHG emission savings, and traceability, the company said. Mass balance accounting is designed to trace the flow of materials through a complex value chain, including recycled feedstock at plants.

Circular value chains and certified feedstocks

“As the largest global manufacturer of black masterbatch, we have the capacity and expertise to deliver innovative solutions that help our customers solve their sustainability challenges as well as meet our own sustainability objectives,” said Jeff Zhu, executive vice president and president, Performance Chemicals segment and Asia Pacific region. “Our new black masterbatch products powered by Evolve Sustainable Solutions will be manufactured at our plants in Pepinster and Loncin, Belgium, which recently achieved ISCC PLUS certification. This gives our customers third-party validation that our products are leveraging circular value chains and certified feedstocks in the product manufacturing process. With several projects at various stages of development, we are excited about our progress and look forward to continuing to collaborate with our customers and industry partners on building out our product pipeline to enable a more sustainable world,” said Zhu.
