engineering plastics business (see page 8). Avient points to its growing portfolio of sustain- able solutions that now include bio-filled polymer grades in its reSound NF family, reSound R recy- cled content thermoplastic elastomers, which have recyclate contents ranging up to 83% coming from post-consumer and post-industrial sources, reSound OM bio-based TPE, and Nymax PIR post-industrial recycled PA 6and 66 formulations with up to 100% recycled polymer content. SABIC in October launched a new portfolio of bio-based Ultem polyetheimide (PEI) resins that offer sustainability benefits while delivering exactly the same high performance and processability as incumbent Ultem materials. The materials are the first certified renewable high-performance, amorphous polymers available anywhere. Based on a mass balance approach, for every 100 kg of Ultem resin produced, SABIC replaces 25.5 kg of fossil-based feedstocks with bio-based materials derived from waste or residue, such as crude tall oil from the wood industry. The new resins are in performance terms exactly the same as current Ultem materials. Scott Fisher, Director, Business Management,
Ultem Resins and Additives, says: “Because these products perform in the same way and maintain the same regulatory listings – such as UL94 and FDA food contact – as traditional Ultem resins, adjustments to product designs and manufacturing processes are not required.” The increasing requirements for the use of more sustainable raw materials present manufacturers of technically complex components and assemblies with new challenges, says compounding group LehVoss. The group says it has taken on this task with its subsidiary WMK Plastics and developed ecological and economical alternatives to virgin materials in the upper third of the material pyramid on the basis of material recycling.
SABIC’s Noryl GTX 9500 is a PPE/PA blend that picks up much less moisture than pure PA6 or 66
The first portfolio of the high-performance polymer PEEK includes six standard recipes which were presented at Fakuma in October. These Luvotech eco PEEK grades are characterised by significantly reduced greenhouse gas emissions with almost the same technical performance compared to new goods and thus offer an alterna- tive for almost all classic areas of application. In cooperation with the SKZ (South German Plastics Centre), a reduction in greenhouse gases of around 55% was demonstrated using the Luvotech eco PEEK GF20 as an example.
“In addition to the ecological advantages, a significantly reduced raw material price also opens up new fields of application in which the use of PEEK was previously not possible from an eco- nomic point of view,” says the company. “For a reliable supply of the highest quality, secure raw material sources are just as important as the more than 35 years of know-how in the development and manufacture of recycled materials, the
