Abstract
A hydrolysis resistant polyamide composition comprising from 50 wt % to 80 wt % polyamide polymer having a theoretical amine end group content of at least 55 μeq/gram; and from 25 wt % to 60 wt % glass fibers. The weight ratio of polyamide polymer to glass fibers ranges from 0.5:1 to 4.0:1. The polyamide composition comprises less than 0.06 wt % copper; and/or from 1 ppb to 0.24 wt % non-copper metal halide compound. The polyamide composition, when hydrolysis aged for 500 hours at 130° C., demonstrates an impact resilience greater than 40 kJ/m, as measured at 23° C.
