SynTherm® – Insulating Materials SynTherm® NPN/130

SynTherm® NPN/130 is a flexible 3-ply insulation consisting of a polyester film with a calandered Nomex® layer.

The proven dielectric properties of the polyester film and the excellent mechanical and thermal properties of the outer Nomex® layers result in a high performance insulating material. The ability of the outer layers to absorb impregnants results in exceptional bonding between all winding components. Smooth and abrasion resistant surface and therefore easy to machine processing.
