Paramyd® Paper

Paramyd® Paper
para-aramid paper
Paramyd® Paper is composed of para-aramid (poly-paraphenylene terepthalamide) for applications that require high strength and thermal stability. Primary applications include components for various end-uses that perform better and last longer than their alloy equivalents. When used as honeycomb cores in marine or aerospace applications, Paramyd® Paper offers lower overall weight, without compromising performance. Paramyd® Paper offers electrical insulating properties which make it an ideal choice for electrical components that require insulating interfaces. Finally, as an insulator Paramyd® Paper can inhibit galvanic corrosion between dissimilar materials such as metals and graphite composites.
