Description

Fibroid Fish Paper

Fibroid Fish Paper is a vulcanized fiber insulation material used in electric motors, transformers, switchgear, and other electrical equipment. It is commonly used for slot insulation, phase insulation, barrier insulation, and insulating gaskets.

The material combines good electrical insulation properties with mechanical strength and flexibility, making it suitable for punching, die-cutting, folding, and other converting processes.
