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.
