Nomex Tape

Product Description

Nomex Tape, also known as Aramid Paper Insulation Tape, is a high-performance electrical insulation material widely used in motors, transformers, batteries, and other high-temperature industrial applications. Manufactured from 100% aramid fiber (Nomex or equivalent), this tape offers excellent dielectric strength, thermal resistance up to 220C (Class H insulation), and outstanding mechanical durability.

It is available in different widths and thicknesses to suit various insulation needs.

Nomex Tape is non-adhesive by default, but can also be supplied with special heat-resistant coatings if required. Its unique properties make it a preferred choice in industries that demand flame resistance, dimensional stability, and long-lasting insulation performance.

Applications of Nomex Tape

• Electrical Insulation: Slot liner, phase insulation, and inter-turn insulation in motors, transformers, and generators

• Battery & EV Industry: Wrapping and thermal insulation in lithium-ion batteries and electric vehicles

• Aerospace & Automotive: High-temperature resistant insulation in wiring harnesses and components

• Industrial Equipment: Used in coils, capacitors, and high-voltage machinery

• Laminates & Composites: Reinforcement layer in epoxy, polyester, and phenolic resin-based laminates

Key Features of Nomex Tape
