Nomex  Tape is an excellent insulator which offers good temperature resistance, dielectric strength, mechanical toughness, and flexibility. It is designed to opeElectrical Machine Phase / Slot Insulation Tapes

Nomex and related aramid polymers are related to nylon, but have aromatic backbones, and hence are more rigid and more durable. Nomex is an example of a meta variant of the aramids (Kevlar is a para aramid). Unlike Kevlar, Nomex strands cannot align during filament polymerization and have less strength: its ultimate tensile strength is 340 MPa (49,000 psi). However, it has excellent thermal, chemical, and radiation resistance for a polymer material. It can withstand temperatures of up to 370 °C (700 °F)..
