Abstract
The present invention relates to a thermoplastic composition that provides improved thermal aging stability. The thermoplastic composition includes a polyamide resin, glass fibers, tin(II) oxalate, and a functional additive. It has been found that a combination of a polyamide resin with tin(II) oxalate and a functional additive produces a superior product demonstrating greater thermal stability than the polyamide resin alone.
