Garlic Press 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 and PPA (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
HVAC Lamellae Application Data: Akulon® PA6 allows for light weight solutions as compared to metal; Akulon® PA6 allows for reliable solutions due to high weldline performance and temperature resistance (better than PP) and to its great surface appearance (better than PA66); Akulon® PA6 allows for cost effective solutions as compared to PA66; Akulon® Ultraflow grades allow even for more cost effectiveness due to 25% cycle time advantage and due to high flowability enabling thinner walled designs
