Corrosion inhibiting thermoplastic alloys

A multi-faced enclosure fabricated from top, bottom and side panels, and wherein the panels are prepared from a moldable formulation comprising the steps of:

• (a) preparing a masterbatch comprising:
• (i) 100 parts of a high temperature engineering plastic consisting of polycarbonate, and
• (ii) between about 5 parts to 20 parts of a vapor phase corrosion inhibitor selected from the group consisting of cyclohexylammonium benzoate, sodium nitrite, benzotriazole, sodium sebacate, and mixtures thereof;
• and
• (b) extending the masterbatch with said engineering plastic resin to produce a working blend comprising at least about 95% said engineering plastic resin, balance corrosion inhibitor.

• (a) preparing a masterbatch comprising:
• (i) 100 parts of a high temperature engineering plastic resin selected from the group consisting of nylon, polycarbonate, and polyethylene terephthalate, and
• (ii) between about 5 parts to 20 parts of a vapor phase corrosion inhibitor selected from the group consisting of cyclohexylammonium benzoate, sodium nitrite, benzotriazole, sodium sebacate, and mixtures thereof;
• and
• (b) extending the masterbatch with said engineering plastic resin to produce a working blend comprising from between about 1% to about 7.5% corrosion inhibitor, balance high temperature engineering plastic resin.
