This laminate is designed not to delaminate or blister at high temperatures. The polyester film in this three-ply laminate contributes high dielectric strength, as well as good initial tear strength and tensile properties. The calendered NOMEX? paper provides long-term thermal stability, as well as improved propagation tear strengths. Application This laminate is broadly used in the manufac- ture and remanufacture of motors and generators of many sizes and temperature classes. The most important applications are for slot liners, wedges and phase insulation in Class H motors and generators, as well as in large and specialty Class F motors. Motor manufacturers as well as motor repair facilities who remanufacture motors like the ability to standardize on Type NMN, and use just one insulation material for all motors. DUPONT? NOMEX?
