Patent number: 9856365Abstract: The present invention relates to a thermoplastic composition that provides improved thermal aging stability along with durability. The thermoplastic composition comprises a polyamide resin, and a polyhydric alcohol, wherein a majority of the polyhydric alcohol particles have a particle size that is less than about 70 microns. It has been found that a combination of a polyamide resin and a polyhydric alcohol with this particle size produces a superior product demonstrating greater thermal stability and durability than the polyamide resin alone.Type: GrantFiled: August 30, 2012Date of Patent: January 2, 2018Assignee: Radici Plastics USA, Inc.Inventors: Sumit Mathur, Mark Elkovitch, Vikram Gopal, Rajeev S. Bhatia
