Akulon® PA6 is a reliable solution for chair frames compared to metals as no corrosion protection coating is needed with PA6. Akulon UltraFlow PA6 yields a better surface appearance than PA66 (even at 50% to 60% GF). Arnitel® TPC is approved for seat suspension, Stanyl® PA46 is approved for bearings and sliding parts, and EcoPaXX® PA410 is a 70 % bio-based alternative.}
