Nylon nanocomposite for barrier tanks.A new nylon nanocomposite is offered as a monolayer mon·o·lay·er n. 1. A film or layer one molecule thick formed at the interface between water and either oil or air by a substance such as a partially esterified fatty acid that contains both hydrophobic and hydrophilic groups in the same solution for small fuel tanks and hoses that are now required to meet more stringent fuel-permeation requirements from the State of California and the U.S. EPA EPA eicosapentaenoic acid. EPA abbr. eicosapentaenoic acid EPA, n.pr See acid, eicosapentaenoic. EPA, n. . NanoSeal nylon from Nylon Corp. of America Inc. (Nycoa), Manchester, N.H., is based on a proprietary nylon copolymer copolymer: see polymer. and incorporates nanoclay platelets that act as a barrier, creating a tortuous path for liquid or vapor to penetrate. The nanocomposite is claimed to be a cost-effective alternative to multilayer HDPE/EVOH structures or fluorination fluor·i·na·tion n. A chemical reaction that introduces fluorine into a compound. . Fuel permeation is reduced up to 97% compared with monolayer HDPE HDPE abbr. high-density polyethylene and 40% versus neat nylon 6. The "super-tough" material also meets low-temperature impact requirements. Several injection and blow molded fuel tanks are being evaluated for small off-road vehicles, lawnmowers, and snowmobiles. One example is a 3-gal tank for a riding mower that is blow molded by Comfer Plastics, Tonawanda, N.Y. Tel: (603) 627-5150 * PT Direct: 991KK [ILLUSTRATION OMITTED] |
