Vulcanized Fiber (Fishpaper)

Vulcanized Fiber (aka Fishpaper – Vulcanized Fiber) is a strong cellulose paperboard insulation. It is used primarily for its excellent electrical insulating properties.

Fishpaper is the name for the electrical grade of vulcanized fiber. Fishpaper properties include light weight, and ease of forming and punching. Fishpaper is unique because it is more resistant to heat and cold than comparable plastic material. Available in thinner gauges, typically from 0.0078" to 0.062" thick; fishpaper's standard color is grey.

Vulcanized Fiber is a hard, durable, chemically pure cellulose product that contains no resin or bonding agents. It offers flexibility, impact resistance, high tear strength and a smooth, abrasion resistant surface. It can be machined, punched, slit, threaded, formed, molded and wound into tubes for literally countless applications. Vulcanized fiber is available from .0078" to 0.375" thick in several colors. Certifies to NEMA Commercial grade per MIL-F-1148, C-H; MIL-F-13526, red sheet.
