Fish Paper (Vulcanized Fibre)
Fish paper is a strong, flexible paperboard that has good mechanical properties. It offers excellent electrical insulating and arc quenching properties. It is a good choice for applications in which moisture is not a factor and where temperatures do not exceed 425 degrees F. It can be die cut and machined.
Fish paper is insoluble in ordinary solvents and is unaffected by ammonia, turpentine, naptha, benzene, petroleum, alcohol and ether. It has superior bending qualities and is especially useful for armature slot insulation.
