DuPont Materials for Electrical Insulation
DuPont™ offers several materials that are ideal for electric insulation in motor, generator, and transformer applications.
DuPont Nomex® is an aramid paper-based material with superb characteristics for electric insulation, as well as thermal protection. Nomex is well-suited for a wide range of electrical insulation applications, including today’s high performance electric motors found in a range of rotating equipment from generators and wind turbines to hybrid and electric vehicles. Nomex also delivers outstanding thermal protection and mechanical toughness.
Nomex delivers the following capabilities: - Decreased rate of failure
- Less energy consumption, especially important in HEVs and EVs
- Improved thermal protection
- Improved reliability, as well as shock and vibration resistance
- Long product life
- Excellent fire resistance
In addition to Nomex, DuPont offers Kapton® and Teijin Films Mylar® for motor and magnet wire insulation. Kapton is a polyimide film that offers: - Dielectric strength
- Thermal performance
- Tensile strength
- Chemical resistance
- Thin film
Teijin Films Mylar is a polyester film used to ensure isolation of wires and components and enhance protection from harsh operating conditions. This material provides: - Strength and toughness with good mechanical forming and easy roll-to-roll lamination
- High dielectric strength
- Resistant against chemical attack
- Good thermal endurance
Fabrico works with DuPont in a variety of applications where electrical insulation and thermal protection/management may be required. Fabrico offers slit, chopped, die-cut, discrete, and multi-layer insulation parts produced from Nomex, Kapton, and Teijin Films Mylar.
DuPont, Nomex, Teijin Films Mylar, and Kapton are Trademarks of E. I. du Pont de Nemours and Company.
