Nomex NPN Class F (155 Degree C)

Triple - layer insulation made from polyester film and Nomex paper overlay on both sides. ln this composite, good mechanical and electrical properties of the polyester film are ideally supplemented by excellent chemical and thermal properties of the Nomex aramid paper. The high specific insulation resistance and di-electric strength do not change to any extent up to 200⁰C for short duration and 155⁰C continuous.
Nomex layers also protect film from high temperature against damaging effect of oxidation and hydrolysis as well as mechanical damages. Impregnating resins bond very well with DUROTHERM.
DUROTHERM is best for manufacturing electrical machines of class F because of high tensile strength, tearing strength, dielectric strength and excellent absorbtion of varnish with temperature rise upto class F.
