Why choose us?
1. Stable and reliable insulation performance
DMD insulation paper has passed international/national standards such as IEC 60626 and GB/T 5591.3, ensuring that it has high dielectric strength, low moisture absorption, and good voltage resistance (we provide SGS third-party product test report).
The dielectric strength reaches ≥ 50kV/mm, which can effectively prevent inter-turn breakdown and is suitable for core equipment such as transformers and motors.
2. High-quality raw material control, three-layer composite is more solid
Select high-quality domestic polyester film (PET) and polyester non-woven fabric, which are tightly laminated, without delamination, powder loss, and warping, and still maintain structural stability under high temperature and mechanical processing environment.
3. Support epoxy pre-preg and hot press curing version (customized)
Provide epoxy pre-preg DMD (B-stage epoxy DMD), which is suitable for hot press curing process, enhances the bonding force with the coil, and improves the overall heat resistance and mechanical strength.
Meet customers' high-end application needs for dry-type transformers and high-temperature resistant motors.
4. Wide range of temperature resistance grades (Class B, F)
Two versions with heat resistance grades of 130°C (Class B) and 155°C (Class F) are available to meet different working conditions and equipment life requirements.
5. Comprehensive customization services, size, thickness, and adhesive can be customized
