MULTILAYER STRUCTURE USEFUL FOR ELECTRICAL INSULATION
摘要
A multilayer structure contains (a) a first layer of aramid and cellulose wherein (i) the aramid is present as an meta-aramid in an amount of 0 to 50 weight percent floc and 50 to 100 weight percent fibrid, (ii) the cellulose is present in the form of cellulosic pulp fiber and (iii) the aramid is present in an amount of 16 to 75 weight percent and the cellulose is present in an amount of 25 to 84 weight percent, said percentages on the basis of the aramid and cellulose and (b) a second layer containing cellulosic pulp fiber with the proviso that the second layer does not contain aramid. The multilayer structure is particularly useful in a transformer.
