Nylon long fiber reinforced

The growth of these materials is reflected in the number of polymers which are being glass reinforced. These include polypropylene, polystyrene, styrene acrylonitrile, nylon, polyethylene, acrylonitrile-butadiene-styrene, modified polyphenylene oxide, polycarbonate, acetal, polysulfone, polyurethane, poly (vinyl chloride), and polyester. In addition, the reinforced thermoplastics available now include long-fiber compounds, short-fiber compounds, super concentrates for economy, a combination of long and short fibers, and blends of polymer and fibrous glass. 

As an example LNP Engineering Plastics, USA has been publishing results of tests that include a selection of die-cast metals compared with a 60 wt% long glass fiber reinforced nylon 6/6 compound (Verton RF700-12EM). The conclusion was that (for moisture-conditioned samples) with a density lower than metals, with the exception of certain... 

Reinforcements. Both the resole and novolac compounds use a broad array of reinforcements to meet the demands of the market place wood flour, cotton flock, minerals, chopped fabric. Teflon, glass fibers (long and short), nylon, rubber, and kevlar. Asbestos, which had been a widely used filler in many thermosetting compotmds, has been replaced over the past 20 years with glass fiber-reinforced phenolic compounds in many applications.

Next came acquisitions, funded in part by the divestitures, that reinforced the learning base in the paths that the firm had long followed. In films and fibers it purchased Exxon s carbon fiber business in 1984, Exxon s film composites activities in 1985, and Hercules s olefin fiber carpets in 1989. Later, in 1992, it traded its acrylic assets to ICI for the latter s nylon business, plus 41 million. In paints and finishes Du Pont obtained Ford s North American automotive paint division in 1986, followed by a joint venture with ICI to expand the same market in Europe, and one with Kami Paint to do so in Japan and East Asia. In agricultural chemicals it acquired Shell s agricultural chemicals division in 1986, and later in 1992 collaborated with Shell to develop specialized insecticides. For Du Pont, sustaining its technical and functional capabilities in long-established paths in which it was a competitive leader remained a basic strategy. ...
