Transformer Flexible Material Epoxy Resin
Epoxy-resin prepreg DMD flexible laminates
DMD pre-impregnated class F material, composed of F-Grade heat-resistant glue for double-sided polyester nonwovens and one layer of polyester film, then soak with heat-resistant epoxy resin and bake. This product has a smooth surface and stable performance. It adheres very well to copper foil and aluminum foil. After winding with copper (aluminum) foil, the low molecular weight and low shrinkage under vacuum drying conditions practically does not evaporate. insulation material for dry power transformers, reactors and other engines.
Hold it about 130 ± 5 ℃ for about 5 hours or 140 ± 5 for about 0.4 hours, or 150 ± 5 for about 3 hours to harden.
