Abstract
Nylon 6 with increased wear life is comprised of a major weight amount of nylon 6 and minor weight amounts of a polyester elastomer, a polyolefin and a polyfluorocarbon.
Claims4
A molding composition comprising a melt blend of:
- a major weight amount of nylon 6, a polymer of caprolactam, and
- 2 to 5 weight percent amount of a polyolefin, 2 to 5 weight percent of a polyfluorocarbon and 5 to 46 weight percent of a polyester elastomer.
A method for improving the wear life of nylon 6 which comprises blending the following:
- at least 50 weight percent nylon 6
- 5 to 46 weight percent polyester elastomer
- 2 to 5 weight percent polyolefin, and
- 2 to 5 weight percent fluorinated polyethylene at temperatures above the melting points of both the nylon and the polyester elastomer for a time sufficient to increase the molecular weight of the blend.
