Abstract: The present invention provides a polyamide composition comprising (a) at least one polyamide mixture formed from (i) at least one polyamide 6,6, the amount of amine end groups (AEG) being greater than the amount of carboxylic acid end groups (CEG); and (ii) at least one high chain-length polyamide; (b) at least one reinforcing filler; (c) at least one heat stabilizer; (d) aluminum stearate; and optionally (e) at least one additive. The polyamide composition can be advantageously used to produce articles exhibiting enhanced chemical resistance, notably CaCl2 salt crack resistance, such as radiator end tank in an automobile.

Abstract: The present invention provides polyamide compositions comprising (a) at least one polyamide mixture; (b) at least one reinforcing filler; (c) at least one heat stabilizer; and (d) at least one ionic lubricant, wherein the (a) at least one polyamide mixture is formed from (i) a polyamide 6,6, the amount of AEG being greater than the amount of CEG, and (ii) a blend of a first high chain-length polyamide having viscosity number (VN) of X1 and a second high chain-length polyamide having VN of X2, X1 being greater than X2. The polyamide composition can be advantageously used to produce articles exhibiting enhanced chemical resistance, notably CaCl2 salt crack resistance, such as radiator end tank in an automobile.
