Abstract: Disclosed herein is a method for improving Inclined Plane tracking (IPT) property at voltage higher than 1 kV by using a polyamide composition. The polyamide composition includes a) 10 to 50 wt % of at least one semi-crystalline aliphatic polyamide having on average, from 3 to 5 carbon atoms, not including the carbon atom in the carbonyl group, per amide group; b) 1 to 40 wt % of at least one long-chain aliphatic polyamide having on average equal to or more than 6 carbon atoms, not including the carbon atom in the carbonyl group, per amide group; c) 0 to 35 wt % of flame retardant; d) 0 to 50 wt % of fibrous and/or particulate filler; e) 1 to 25 wt % of impact modifier, and f) 0 to 20 wt % of other additives.
