Aramid Paper · Electrical Insulation

Nomex 410 for thermal and electrical insulation.

Dielectric strength up to 500 V/mil, UL 94V-0 certified. Precision laser cutting, no minimum order, fast delivery from Montreal.

Overview

The reference aramid paper for the electrical industry.

Nomex 410 is a thermosetting aramid paper introduced in the 1960s. Made from resin-impregnated aramid fibers, processed under pressure and heat, it produces a strong, stable, flame-retardant material.

It meets UL 94V-0 standards and MIL-I-24768/28 GEB-F requirements. Its dielectric strength — the best of all the materials we work with — makes it essential for high-performance electrical applications. P&P Colorismédia can source it in various thicknesses and configurations to fit your project.
