FISHPAPER & VULCANIZED FIBRE for insulation

Fish Paper Vulcanized Fiber
Fish paper – or Fishpaper – is a type of fibrous dielectric paper known for its unique combination of strength, ease of forming and punching. Fishpaper is also unique because it is more resistant to heat and cold comparable plastic materials. Electrical-grade Fishpaper is a vulcanized fiber material that is frequently used for electrical insulation and is commonly die cut to create unique parts for specific applications. Vulcanization is a chemical process that transforms rubber or other polymers into more durable materials via the addition of accelerators or curatives.

Fishpaper Characteristics
Fishpaper contains various properties that make it well-suited for use in the manufacturing of electrical insulation materials. It offers high mechanical strength and greater resistance to extreme temperatures than most types of plastic materials. Fishpaper is also extremely light – it’s approximately half the weight of aluminum, which makes it an excellent choice for applications where reducing weight is essential for ensuring peak product performance and maximizing fuel efficiency.

Other valuable characteristics include excellent tensil strength and good arc resistance and the ability to be machined easily with traditional tools – you cannot machine Fishpaper. While the material is often sold in the form of sheets, it can also be found in coils or rolls that facilitate automatic punching.

Fishpaper Applications
In addition to being used to manufacture electrical insulation, examples of other applications of electrical grade fishpaper include:

• Electrical instruments
• Appliances
• Various automotive parts and components
• Electronic devices
• Fuse tubes
• Circuit breakers
• Gaskets
• Motor contact bushings
• Railroad track insulation

Die Cut Fishpaper
Our vulcanized fiber sheet die-cutting methods can create custom fishpaper parts for your unique applications. We can work with your drawings, blueprints or specifications to develop a superior product that will exceed your performance and durability expectations.

Our die-cutting techniques include rotary die cutting, which is normally the best option for producing components such as gaskets and many types of automotive parts, and steel rule die cutting, which offers an extremely cost-effective procedure for mass-producing custom die components. We can also perform highly advanced fishpaper insulator laser cutting, which is the best choice for complex or high-precision components.
