Abstract
Corrosion inhibiting thermoplastic alloys and methods of preparing same for use in fabricating molded articles with long-term corrosion protection. Masterbatches of nylon, polycarbonate, and polyethylene terephthalate high temperature engineering plastic resins together with selected corrosion inhibitor formulations are extruded for use in injection molding operations Molded articles are prepared from the high temperature engineering plastic resins and a solid phase corrosion inhibitor blended in situ, and wherein the resin consists essentially of nylon, polycarbonates, and polyethylene terephthalate, and wherein the corrosion inhibitor contains a blend of corrosion inhibitors such as cyclohexylammonium benzoate, sodium nitrite, benzotriazole, and sodium sebacate.
