Grade: DuPont™ Nomex® T411
Formula: Polymetaphenylene isophthalamide
Form: Foil/Film/Sheet
Material: Polyaramide
Commodity: Polymers
DuPont™ Nomex® T411 Polyaramid film is a thin and flexible polymetaphenylene isophthalamide sheet from Goodfellow's range of films. It exhibits high thermal stability and chemical resistance. The aramid polymer film has low flammability and is often used in electrical insulation, flame barriers, and heat shields. With its combination of strength, heat resistance, and dielectric properties, Nomex film serves well as an electrical insulator and protective barrier from extreme temperatures.
