fishpaper vulcanized fibre

At NEDC, insulators are one of our core products. Many different electrical insulation materials are among products we cut into custom shapes. However, fishpaper, and vulcanized fiber paper products are among the most popular electrical insulation materials we use. 

Properties of Fishpaper/Vulcanized Fibre

Fishpaper/vulcanized fiber is a lightweight, fibrous material that is easy to cut, and form into shapes. It is mainly used an electrical insulator. Certain fishpaper/vulcanized fibre products are fire retardant, and certified to UL 94 V0 in some cases. For example, Vulcanex- Oliner Fibre brand of Vulcanized Fibre is certified to UL 94 V0. Electrical grade vulcanized fibre is referred to as fishpaper. They feature high dielectric strength, and high volume resistivity.  However, its good to note, because it is a paper type product, the temperature range is fairly low usually. 

Specifications that can be met by Fishpaper

-MIL-I-695 Type F

-ASTM D710




Why use it & for what Applications?

As an electrical insulator, many times it is used as such, but it can be used for:


-Electrical Insulation in electrical appliances

-Fuse tubes

-Circuit Breakers

Perforations/Bend Lines

Oftentimes, we will get customers who ask for bend lines, or perforations to be placed into the part. The ability to do this depends on the geometry of the part- however typially we are able to do both perforations or bend lines to accomodate customers requirements. 

More Information on Fishpaper

As always, adhesive backings such as 3M tapes are available with these products. Tapes such as 3M 9472, and 3M 467MP are a common choice by customers. These papers are available in several different colors, however common colors include dark blue, and light grey. Thicknesses of these materials are available from .005’’ to .062’’ in thickness. NEDC uses laser-cutting, and die-cutting to cut paper products into custom shapes such as washers, and other shapes. For more information on fishpaper, or vulcanized fiber, please contact
