Right: Avient has launched Maxxam recycled and bio-based materials
and bio-based polyolefin formulations that can replace traditional polyolefin materials in a range of applications including transportation, industrial, electrical and electronic, building and construction and consumer industries. Maxxam REC is a recycled polyolefin formulated with 25-100% recycled resin from post-industrial recycled and post-consumer recycled sources. The Maxxam REC grades are offered in darker shades. Maxxam BIO polyolefins are formulated with 15-100% bio-based resin and/or natural filler from renewable plant sources. Maxxam BIO formulations are natural and are easy to colour. The new formulations are fully customisable and can be filled and reinforced or blended with glass, minerals, impact modifiers, colorants and stabiliser systems to meet specific application needs, including flame retardant performance. Avient also announced the availability in Europe
of its Nymax BIO bio-based polyamide formula- tions. The material was manufactured at the company’s Shanghai facility when it was initially launched. The grades are now made in Avient’s facility in Germany. Nymax BIO comes with formulations between 16% and 47% natural filler from renewable plant sources, including corn, straw and wheat.

portfolio of electroplating materials made with renewable or recycled feedstocks. These electro- plating ABS and ABS/PC blends are used in the automotive industry and sanitary applications. Electroplating is a process that is very sensitive to impurities in the plastic substrate, which are often present in mechanically recycled plastics. But using chemical recycling and bio-processes for feedstocks means Elix can produce plastics in which the performance of the substrates is identical to the petroleum-based versions. All the characteri- sation data for the standard grades applies also to the new ones, including flow simulation and crash material cards.
The more sustainable electroplating portfolio includes the following grades: E-Loop P2MC CR50, E-Loop HH4115PG CR25 and E-Loop HF4200PG CR25, including a high flow ABS and two ABS/PC grades with higher thermal resistance and impact resistance than ABS, and two different levels of flowability. The sustainable content of these grades are currently 50% for the ABS and 25% for the ABS/ PC, but there is potential to increase those contents in the short-term, says Elix. The company has undertaken a full Life Cycle Assessment (LCA) validated by the Anthesis group to investigate the environmental performance of its more sustainable E-Loop products and to compare them with fossil-based polymers. The LCA shows that mechanically and chemically recycled products can considerably reduce the environmental impact of the final product, says Elix. Ineos Styrolution has developed new specialty solutions and sustainable plug-in solutions that replace virgin materials and are said to be of interest to the automotive industry. The material developments reflect the continuing industry transition embracing e-mobility and new fuels like hydrogen, which is prompting brand owners to seek sustainable materials to be introduced in their next generation vehicles. At the K show, Ineos Styrolution presented
results of its first tests with a new Novodur ECO HH-106 MR 30 grade that contains 30% mechani- cally recycled content. A B-pillar and a rear light housing made from the material were exhibited. The company’s Luran S materials are also now available as a sustainable solution. The Luran S ECO grades have up to 50% bio-attributed content with the process ISCC Plus certified. The material allows automotive application designers to reduce the ecological footprint of their designs. Other advances include a new SPF 60 modifica- tion that introduces the next generation of UV
