Electrical cable insulation composed of silicone rubber was deteriorated by the nibbling and biting action of some marine animals. White polyvinyl chloride insula- tion changed to black when exposed to hydrogen sulfide produced by su I fate-reducing bacteria in the mud. 7. The following materials in various forms and for various uses were not affected by marine organisms: unplasticized polyvinyl chloride pipe; butyl rubber, neoprene, natural rubber, plasticized polyvinyl chloride, nylon, fluorinated ethylene propylene, GR-S rubber, and Teflon electrical cable Insulation; various plastic laminated sheets; glass microscope slides; rubber vacuum tubing; nylon nuts and bolts; nylon and poly- propylene ropes; ethyl cellulose cable clamps; and a plastic, pressure-sensitive electrical insulation Figure 43. Sections of white polyvinyl chloride insulation exposed to bottom mud had changed to black. 44.
