Abstract:

The successful longterm operation of the Australian designed Mulloka sonar system was found to be dependent on the correct choice of material for an elastomeric membrane intended to prevent moisture ingress into the underwater transducer array. The amount of moisture removed after a period in service was in good agreement with the amount predicted from laboratory measurements. A study of the influence of compounding ingredients on the water vapour permeability of bromobutyl rubber vulcanizates was carried out in order to produce low permeability elastomeric membranes for sonar applications. The factors affecting the water vapour permeabilities of nitrile rubber vulcanizates are reported here for the first time. Author
