Flexible Electrical Insulation Materials

ATS supplies a wide range of flexible insulation laminates including DMD, NMN/NPN, Mylar® polyester film, and varnished glass cloth. These high-performance materials are commonly used in motor slot insulation, transformer barriers, and electrical winding protection.

Our laminates are available in Class B, F, and H temperature ratings and offer excellent dielectric strength, mechanical durability, and thermal resistance for industrial electrical insulation applications. They are often used in combination with insulating varnishes and resins, insulation sleeving, and rigid laminates for complete motor rewind and electrical assembly systems.
