Abstract

Cast PA6 (magnesium-polyamide 6 (MgPA6)) compounds produced using a magnesium catalysis are presently replacing other polyamides in semi-finished engineering products. Because of this increased use, the flammability of MgPA6 containing montmorillonite, graphite, carbon black, and a plasticizer is investigated. In these studies, we observed that the presence of montmorillonite deteriorates rather than improves the flame-retardant properties of MgPA6. We also noted that the presence of a plasticizer enhances the dripping tendency and consequently the burning rate of PA6 in the UL 94 Test for Flammability of Plastic Materials. In addition, the presence of carbon black reduces the fire performance of the resin while graphite improves the UL 94 classification of PA6 to a V-2.
