ED: EDHD copper Foil, RA:Rolled Copper Foil. 1). Nomex® Laminates type NKN is triplex laminates constructed of calendered Nomex® paper bonded to Kapton® polyimide film with a proprietary high temperature adhesive system. Buy 0. In the current work, a series of black polyimide (PI) films with excellent thermal and dimensional stability at elevated temperatures were successfully developed.
