bearing brackets and A-, B- and C-pillars, as well as lightweight battery trays for electric vehicles. Lanxess says its HPM business will gradually
increase the number of “Eco” product types certified in accordance with the mass balance method. It plans to launch a new 30% glass fibre reinforced PA6 with a reduced carbon footprint, for example, using caprolactam “based on a selection of petro- chemical raw materials which support this concern”.
PCR and PIR Avient Corporation (previously PolyOne) recently launched post-consumer recycled (PCR) and post-industrial recycled (PIR) portfolios under the ReSound R brand name. First products are Re- Sound R VX TPEs, ReSound R ND polyamides, and ReSound R PC polycarbonates. The ReSound R ND formulations contain 100%

PCR resin, and are available in both PA6 and PA66 grades with various levels of glass fibre and mineral reinforcements. These products are targeted at applications in the consumer, automotive and powersports markets. They are commercially available in North America now. Avient says global availability is under evaluation and will depend on regional sourcing capabilities. For the Asia market, Avient now offers ReSound
R PC, a range of polycarbonates with glass filler levels from 10 to 30% and recycled content ranging from 25 to 75%. The company says several grades perform on par with virgin PC in terms of tensile elongation, tensile strength, notched Izod impact, flexural modulus, and flexural strength. Global availability is under evaluation here too. At Teknor Apex, ETP Division Director of Specialty Products Pratik Shah says that across markets served by the company, two trends are driving ETP product development: the need for

Recyclon brand of polyamides. The company is launching two new series: the Recyclon AG series of glass-reinforced PA66 compounds with 50% PCR resin content; and the Recyclon BG series of glass-reinforced PA6 compounds with 100% PCR resin content. “These materials are tailored to exhibit near-prime performance and are excellent candidates for a broad range of automotive and consumer applications,” says Shah. He highlights the consistency in processing and end-use performance of the new materials. In measurement of tensile strength, for example, a 33% glass-filled Recyclon PA66 compound exhibits minimal property variation in the course of 80 production runs (see graph left). In September, Ascend Performance Materials completed its acquisition of Italian compounders Poliblend and Esseti Plast (announced in February but delayed because of Covid-19), extending its reach beyond its core PA66 business into other engineered plastics, recycled plastics and master- batches. “Poliblend and Esseti Plast complement our
current business exceptionally well,” says John Saunders, Ascend’s Vice-President for Europe. Poliblend’s portfolio covers recycled and virgin PA66, PA6 and POM (acetal), and Esseti Plast has extensive masterbatch operations. “This acquisition, coupled with our new com- pounding facility in China, will allow us to serve our customers locally around the globe,” says Phil McDivitt, Ascend’s President and CEO. “We now have production, product development and testing capabilities in North America, Asia and Europe.” Tisan Engineering Plastics produces a wide range of engineering plastics based on different
