Description

Vulcanized Fiber / Fish Paper Which Combines Impact Strength, Resilience And Electrical Insulation Properties

Fish paper is a durable, flexible, electrical insulator that’s made of vulcanized fiber and used with motor windings and for gasket insulation. A lightweight dielectric paper, this electrical grade material is also a good choice for oil-filled transformers. Moisture absorption can cause fish paper to swell or curl.

0utstanding dielectric properties

Fish paper electrical insulation has good mechanical strength because it’s fibrous

This hard, wear-resistant cellulosic paper is more heat-resistant than many plastic materials

Retains greater flexibility than plastics at low temperatures
