Product Applications

Product Description:

DK soft composite is a two-layer flexible laminate formed by coating one side of a polyimide film with a high-temperature‑resistant adhesive and laminating it to a polyester fiber nonwoven fabric.

It exhibits excellent heat resistance and favorable mechanical properties, making it a reliable Class H insulating material.

It is suitable for use in electric motors and electrical appliances as slot insulation, turn-to-turn insulation, liner insulation, and as an insulating wrap for copper (or aluminum) wires.
