6641 F-CLASS DMD Insulating composite paper
As a Class F insulating material (long-term operating temperature of 155°C), 6641 DMD excels in high-temperature environments. Its core layer uses a high-melting-point polyester film (e.g., 6020 electrical insulation polyester film), combined with Class F adhesive, which remains intact (no delamination or blistering) for 10 minutes at 180±2°C. This heat resistance makes it suitable for high-load motors, dry-type transformers, and other equipment, maintaining stable performance even during short-term overloads (e.g., 200°C).
