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.

Abstract: The present invention relates to a polyannide composition comprising polyamide, polyketone, and rubber, wherein the polyketone is present in an amount of no more than 5 wt %, based on the total weight of the polyamide composition. The inventive polyamide composition has and exhibits improved mechanical properties and chemical resistance both to Zinc salt and glycol, and thus is particularly useful in the manufacture of articles for automotive application.
