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: A resin blend composition of a polyamide resin and a polyester resin is described, which includes a polyamide resin, a polyester resin and an epoxy resin. The resin blend composition can have improved compatibility between the polyamide resin and the thermoplastic polyester resin, and therefore mechanical properties (strength, bending strength, elasticity, abrasion resistance, impact strength), chemical properties (solvent resistance), thermal resistance, dimensional stability, and paintability.
