Carpet nylon may yield blends.(News)

Plastics News, June, 2007

Byline: Bill Bregar Nylon 6, taken from scrap carpet, can be successfully blended into wood-plastic composites, according to research from the Atlanta-based Georgia Institute of Technology. Nylon 6/6 does not work as well, because the wood fibers degrade. Nylon is well-established for use with fiber-reinforced composites, but not for deck board or other products that use natural fibers.

The reason? Wood and other natural fibers degrade and burn at temperatures above 392[degrees]F, which is well below the melting points of nylon 6 (437[degrees]F) and nylon 6/6 (509[degrees]F). Conventional wisdom was that high melting point means nylon is not suitable for use in wood-plastic composites, said John Muzzy, a professor and chairman of polymer engineering at the...
