Diamond dotted paper, or DDP, is made of electrical insulating paper with diamond-shape epoxy resin dotted on both sides.

The epoxy used in diamond dotted paper contains a kind of incubative hardener material. It is a dry and crisp material at normal temperature.

Diamond dotted paper has good dielectric properties and good mechanical properties after heat solidification.

Diamond dotted pattern paper  is used in oil-immersed transformers for the insulation between coils and layers of oil immerged power distribution transformers.
