vulcanized fiber gaskets, seals, and washers using our die cutting, punching and stamping capabilities. Vulcanized fiber is a hard, durable, chemically pure cellulose product that contains no resin or bonding agents. Vulcanized fiber is made between .0078″ and .375″ thick. It is produced in several grades and colors. The electrical grade of vulcanized fiber is referred to as fish paper. Vulcanized fiber has superior flatness, high mechanical strength, and excellent resistance to heat and cold. It is light weight, has excellent tear resistance, and can be machined with standard tools. It can be machined, punched, slit, threaded, formed, molded and wound into tubes for literally countless applications.
Vulcanized fiber can be used for washers, insulating plates, switch and appliance insulation, electric motor insulation, gaskets, automobile parts, luggage, patterns, and many other applications.
Fish paper is a strong paperboard insulation used primarily for its excellent electrical insulating properties. Fish paper is the name for the electrical grade of vulcanized fiber. Its unique properties include that it is lightweight, and very easy to form and punch. It is great for gasket applications, washers and spacers. Fish paper is used extensively for electrical insulation applications due to excellent arc resistance. It is also non-magnetic and resistant to solvents, oils, grease, corrosion, wear and abrasion. Fish paper is machine-able without splintering, ripping or cracking.
Fish paper applications include: electrical appliances, instruments and insulators, washers, electrical devices, gaskets, fuse tubes, slot insulations, arc shields, coil insulations, insulation washers, circuit breakers, bushings for motor contacts and lightening arresters
