Impregnated Prepreg F-DMD Insulation Paper

DMD Epoxy Prepreg Insulation Paper (F type) is formed by impregnating the modified F type DMD with high temperature resistant epoxy resin to B level, and pre-curing after baking, which is a high-performance insulation material, with a long shelf life at room temperature, low pre-curing temperature and time, and exhibits excellent electrical insulation, bonding and heat resistance.

This innovative composite pre-impregnated DMD paper design uniquely combines the mechanical robustness and impregnation capabilities of polyester fiber with the superior dielectric properties of polyester film. The resulting material delivers exceptional heat resistance, outstanding dimensional stability, and reliable resistance to chemical corrosion.

Advantages of Prepreg F-DMD insulation paper:

1. Superior Electrical Insulation

Possesses excellent dielectric properties, effectively preventing current leakage and short circuits to ensure the operational safety of electrical equipment.

2. Exceptional Thermal Stability

Rated for Class F thermal endurance, it maintains stable performance at elevated temperatures with minimal risk of aging or deformation.

3. Effective Flame Retardancy

Offers excellent flame-retardant properties, helping to inhibit flame propagation and provide critical protection in emergency situations.

4. High Mechanical Strength

Exhibits remarkable tensile and tear strength, enabling it to withstand significant mechanical stress without damage.

5. Excellent Adhesion

Bonds securely to equipment surfaces, ensuring perfect contact between the insulation layer and substrate for optimal performance.

6. Environmental Compliance

Manufactured from eco-friendly materials that are harmless to human health, meeting stringent environmental standards.

7. Customizable Specifications

Available in various thickness and width options to meet specific application requirements across different electrical equipment.

Application of DMD Epoxy Pre-impregnated Paper:

It is used for the lining insulation of copper/aluminum foil low-voltage coils in dry-type transformers, as well as slot insulation and phase-to-phase insulation in B~F motors and electrical appliances.
