Polyaromatic Amide Fiber Paper(abbr.: aramide paper)& Polyester FilmCompositesare a??family of 2,3-ply??laminates of NOMEXTM paper bonded toone or bothsides ofpolyester film. It has not only the excellent dielectric??and mechanical strength of film’s,but the better tear resistance and excellentabsorption tovarnishof paper’s,so it is a reliableclass-F insulation material for electrical machines.?
?
Note: NOMEX paper is commodity name of Dupont’s aramide paper
Insulating materials NMNCharacters:
*Excellent dielectric and good mechanical strength. *Good heat resistance, can work for a long term under 155℃for F, H-class insulation. *Better flexibility and very good applicabilityin slot insulation *Low dielectric dissipation, can work in harsh conditions.
