Abstract: The invention relates to a ternary blend having a core/shell structure including (1) PA as a matrix, and (2) a core/shell particle. The ternary blend includes 60-80 wt % of PA and 20-40% of core/shell particle based on the total weight of the ternary blend. The shell is EPDM-g-MA, and the core is PP or PC.

Abstract: Described herein is a polyamide composition, including: (A) 10 to 60% by weight of a polyamide, (B) 10 to 60% by weight of a polyketone, (C) 5 to 25% by weight of a flame retardant, and (D) 0.5 to 10% by weight of a flame retardant synergist, each being based on the total weight of the polyamide composition, where the polyamide has at least one type of structural units of more than 6 carbon atoms. Also described herein is an article produced from the polyamide composition.

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.
