  • Patent number: 9856365
    Abstract: 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.

  • Publication number: 20160280916
    Abstract: A thermoplastic composition comprising from about 50 to about 99 by weight percent of a nylon 6,6 resin, from about 1 to about 50 by weight percent of a polymer performance modifier and about from 0.01 to about 25 by weight percent of a silicone based additive, wherein the silicone based additive comprises an ultrahigh molecular weight siloxane polymer that is unfunctionalized and non-reactive with the polyamide resin, wherein the thermoplastic composition has an impact strength value which is greater than the combination of the polyamide resin and the polymer performance modifier or the combination of the polyamide resin and the silicone based additive and wherein the thermoplastic composition has an ultimate tensile strength that is at least 80% that of the combination of the polyamide resin and the polymer performance modifier.
