Frequently Asked Questions

What is fish paper used for?

Fish paper provides flexible, durable insulation, commonly used in electrical equipment, transformers, and light fixtures. It is made from vulcanized fiber and offers excellent dielectric strength and mechanical durability.

Can EMI produce custom shapes and sizes?

Yes! We offer die-cutting, scoring, perforating, laminating, and kiss-cutting to create the exact part you need, whether in sheet, roll, or intricate shape formats.

Do you offer adhesive-backed materials?

Absolutely — we laminate adhesives to papers and films, enabling peel-and-stick applications for fast and easy installation in manufacturing environments.

What thicknesses are available?

Materials are available in thicknesses from .005″ to .062″, with additional options available based on application requirements. We slit, sheet, and die-cut materials to meet tight tolerance specifications.

What other materials do you carry?

Nomex®: A high-temperature, flame-resistant material offering outstanding mechanical toughness and dielectric performance, ideal for demanding electrical insulation applications.
Mylar®: A strong polyester film known for its excellent dielectric strength, chemical resistance, and mechanical flexibility, widely used for insulation and protective layering.
Forbon®: A vulcanized fiber product made from pure cellulose, offering exceptional internal bond strength and resistance to delamination, even when exposed to water or high humidity.
