AHA Insulation Paper Description
Brief introduction of the AHA Insulation Paper
The AHA Flexible Laminates is a three-layer flexible composite material, made by the polyimide film with hot rolling aramid paper on both sides. The AHA insulation paper is one of the most exclusive electric insulation materials at present. It has excellent heat-resistant, dielectric property, and superior mechanical properties.
Composition:
AHA-H consists of gold polyimide film, covered on both sides with aramid paper that made in China.
Properties:
AHA shows excellent mechanical properties like high tensile strength and high edge tear resistance combined with electrical properties.The AHA has a smooth surface which allows a trouble free manufacture of low voltage motors when coil shooting machines are used. Heat resistance is class H.
