Document Type and Number:
WIPO Patent Application WO/2013/065467
Kind Code:
A1
Abstract:
The present invention relates to a novel aramid-polyolefin laminate which has excellent mechanical characteristics, electrical insulating properties, dielectric characteristics, liquid impregnation properties and the like and is suitable for use as an insulating member for superconducting devices that are used at low temperatures. This aramid-polyolefin laminate is characterized by being formed into a laminate structure that contains a polyolefin in the form of layers in a layer of aramid paper which is formed of aramid fibrids and aramid short fibers and by having an air permeability of 10,000 seconds or more, said aramid-polyolefin laminate being also characterized in that at least a surface of the layer of aramid paper in contact with the polyolefin layer is impregnated with the polyolefin.
