DMD-F6641 polyester film and polyester fiber nonwoven composite insulation is engineered for high-temperature, high-load electrical environments where superior electrical insulation and mechanical performance are required. The three-layer composite construction—polyester nonwoven + polyester film + polyester nonwoven—provides a balance of strength, dielectric reliability, and thermal endurance suitable for continuous operation at 155°C. This material is commonly used in industrial motors, transformers, electric tools, generators, coils, and various electromechanical systems operating under demanding conditions.
