POLYESTER FILM/POLYESTER-FIBER PAPER COMPOSITE(DMD)
It has good dielectric properties, high heat resistance and mechanical strength. It is suitable for small and medium size of electric machines as slot, backing insulation etc. of “F” class (155°C or 311°F) appliances.
DIAMOND DOTTED FILM (D.D.F.)
Made of electrical insulation polyester film dotted with special epoxy resin on one side. This flexible material has good dielectric properties and good mechanical properties. It is suitable for oil-liquid or dry transformers as insulation material between layers.
DIAMOND DOTTED PRESSPAPER (D.D.P.)
Composed of electrical insulation paper with diamond-shape epoxy resin dotted in both sides. The epoxy resin used in D.D.P. contains a kind of incubative hardener material. It is a dry and crisp material at normal temperature (below 35° C or 95° F).This flexible material has good dielectric properties and  good mechanical properties after heat-solidification. It is suitable as insulation material for coils and between layers of coil in the oiled–liquid power and distribution transformers.
