SynTherm® – Insulating Materials SynTherm® NP/50

SynTherm® NP/50 is a flexible 2-layer insulation made of polyester film with calandered Nomex® overlay.

SynTherm® NP/50 is a high-class insulation material due to the proven electrical properties of the polyester film and the excellent mechanical and thermal properties of the outer Nomex® overlays. The outer overlays’ impregnant absorptivity allows excellent bonding of all winding components.
