Flexible Laminates DMD-F-Class
Laminates are basically a material made combining two or more layers of material. We, at Ganapathy Industries are offering Flexible Laminates DMD-Class F with the assurance of best quality. This DMD-F Class flexible laminate has three layers, which are made of polyester film (having high melting point), hot-rolling polyester fiber non woven fabric laminated with Class F Adhesive. This polyester non-woven flexible laminate has outstanding thermal resistance, and dielectric strength. It also has good properties of impregnated, mechanical and electrical. The type of flexible laminate is available in different thicknesses, which can effectively and efficiently serve major insulation applications. Some of the common applications of Flexible Laminates DMD-Class F include slot insulation, linear insulation and interphase insulation in F Class electrical motors.

Superior Thermal and Electrical PerformanceDMD-F-Class flexible laminates are formulated to withstand demanding conditions in electrical machines. Their Class F thermal rating (155C) ensures reliable performance at elevated temperatures, while their high dielectric strength guards against electrical breakdown. The combination of mechanical robustness and consistent insulation properties translates to safer and more durable electrical assemblies.
Versatile Application and CustomizationThese laminates are suitable for various insulation needs, including slot, phase, and liner insulation in motors and transformers. Standard rolls measure 50 meters in length and 1000 mm in width, but customization options for width and thickness are readily available to fit specific requirements. This adaptability is ideal for manufacturers and service providers.
Quality Construction and HandlingProduced with polyester film and non-woven polyester fabric through advanced bonding technology, DMD-F-Class laminates feature smooth, uniform surfaces and high flexibility. Their opaque white color aids easy identification, and their moisture-resistant properties ensure durability throughout shelf life and installation. Storage in dry, clean environments preserves material integrity.
