Today, recycled polyamide (PA) from items like old fishing nets is also increasingly used in sportswear, swimwear, and other garments. For yarns produced with recycled polymer content, the tracers can also be added to the shredded PET/PA material before it’s extruded into polymer pellets, which can offer more flexibility for yarn producers.

This includes Trilliant HC8910 glass-filled polyketone (PK) formulations with a lower carbon footprint than traditional nylon (PA6 and PA66) formulations for a high-performance alternative in applications such as biopharmaceutical clamps.

Nymax™ REC Recycled Nylon Formulations: two new super tough PA6 and PA66 grades added to Avient’s recycled content portfolio, each containing post-industrial recycled content, resulting in up to 81% lower cradle-to-gate product carbon footprint than traditional alternatives made without recycled content, and will be presented during Avient’s technical seminar at NPE, “Exploring Sustainable Alternatives to Traditional Polyamides,” by Jeremy Gray, Application Development and Technical Service Engineer, Specialty Engineered Materials at Avient, on May 9 at 11 a.m.
