THERMAL EFFECTS OF ORGANIC MATERIALS ON METALS AND METALLIC FINISHES.

Abstract

The report covers the evaluation of some 27 AIEE Class B (130C) type organic materials for their thermal effects on metals and metal finishes. Gaskets, electric insulation, plastics, sealing compounds and structural adhesives were investigated in contact with, and in confined close proximity to 9 protective metal finishes, i.e., steel, aluminum, anodized aluminum, cadmium plate, chromated cadmium, zinc plate, chromated zinc, magnesium and copper. Materials were tested at a temperature of 250F.for 60 days. Rubber-asbestos gasket materials in general were the most corrosive and insulated wires the least corrosive materials tested. Cadmium plate and magnesium were the finishes most susceptible to corrosion by the test materials and anodized aluminum the least affected finish. Normally the most severe corrosion occurred in the contact areas. (Author)
