Grade: DuPont™ Nomex® T411
Formula: Polymetaphenylene isophthalamide
Form: Coil
Material: Polyaramide
Commodity: Polymers
Production Method:
Uncalendered Paper
DuPont™ Nomex® T411 Polyaramid Coil (Polymetaphenylene isophthalamide) is a heat-resistant and strong synthetic aromatic polyamide foil offered by Goodfellow within their wide range of specialty foils. With its high tensile strength and thermal stability, Nomex® T411 is well-suited to electrical insulation applications where resilience at high temperatures is required. It also finds use as a dielectric film in capacitors and as a flexible printed circuit substrate where its dielectric properties are valuable.
