Fishpaper is the generic name for the Electrical Insulation grade of Vulcanized Fibre. Fishpaper has unique properties, including light weight, and ease of forming and punching. Fishpaper is also unique because it is more resistant to heat and cold than comparable plastic materials. Fishpaper has excellent punchability and physical strength, for applications like end laminations for electric motors. It is available in sheets, rolls, or slit to coils of any width. Services also include: die-more
