Twisted Multifilament Nomex Thread

Twisted Multifilament Nomex® Thread A-A-50195

While both Kevlar® & Nomex® fibers are chemically similar, they are different in some ways. Nomex® is extremely heat resistant. It will not char at temperatures higher than 675 degrees Fahrenheit. This makes it extremely desirable in safety garments used in potentially high heat applications.

Fiber Type Nomex®
Thread Construction Multifilament
Sizes Available Medium: T-40, T-60
  Heavy: T-90, T-135
  Extra Heavy: T-210
