An apparatus for thermogravimetric analysis TGA is described. The effects of elastomers as coatings on cotton and nylon fabrics were studied by TGA. Fabric samples were double-coated with butyl rubber, Neoprene-W and Hypalon-20. TGA curves were obtained in air and in nitrogen for all samples to include those of the separate component materials. A good correlation was found between TGA data and previously obtained DTA data. The results indicated the cotton-butyl rubber and nylon-butyl rubber systems to have the greatest thermal stability whereas the Neoprene coated fabrics were the least stable. The most pronounced chemical interaction occurred between Neoprene and the two textile substrates. Some chemical coating interaction was indicated for the butyl rubber-coated samples with the least interaction observed where Hypalon-20 was used as the coating. The chemical interaction mechanisms were indicated to be largely nonoxidative in character.
