Chair Arms Application Data: Akulon® PA6 allows for light weight, cost effective solutions in comparison with metals (no corrosion protection coating needed with PA6); Akulon® (UltraFlow) PA6 allows for great appearance solutions, since it yields a better surface appearance than PA66 (even at 50-60%GF); Akulon® UltraFlow PA6 allows for even more cost effective solutions, since it yields faster molding than standard PA6 and enables thinner wall designs
