What is Fish Paper?
Fish paper is a type of vulcanized fiber widely used for electrical insulation. It is durable, lightweight, and offers excellent dielectric strength, making it a preferred material for electrical engineers and manufacturers.
Key Benefits:
- Dielectric strength up to 2000 volts per mil
- Excellent arc and heat resistance
- Easily die-cut, punched, or formed
- Made from high-purity cotton-based fiber
