DuraFab® Premium Kevlar® belts excellent choice in the most demanding environments


DuraFab® Industrial Kevlar (50 Series)

DuraFab® Premium Kevlar® belts are manufactured from woven Kevlar® substrates that have been coated with PTFE (Fluon®). These products have dramatically higher tensile and tear strengths for heavy duty belting applications and are more resistant to steam than fiberglass. DuraFab® Premium Kevlar® belts leave minimal fabric impressions. They offer flexibility and conformity in high-speed applications, which require excellent strength to weight ratio. DuraFab® Premium Kevlar® belts are an excellent choice in the most demanding environments where extreme strength, high loading, resistant to steam and long wear life is required.

DuraFab® Premium Kevlar® Belting Properties

DuraFab® Premium Kevlar® Fabrics are engineered to maintain their unique flexibility, dimensional stability, dielectric and tensile strength, and non-stick properties, while performing under the harshest environmental conditions. AFC’s fabrics are abrasion, tear, puncture, fire and chemical resistant; they also maintain their unique properties under pressure and extreme temperatures: -100° F to 575° F (-73° C to 302° C). DuraFab® Premium Kevlar® Fabrics have received USDA and NSF approval for direct food contact and are FDA compliant (21 CFR177.1550).


  • Kevlar® is 5X stronger than steel on an equal weight basis, but lightweight & flexible at the same time.
  • High tensile strength at low weight
  • Higher UV resistance than glass
  • Experiences no embitterment or degradation at –320 deg. F (same with Nomex)
  • Kevlar® is an excellent fabric choice for use in high moisture environments

Additional applications exist. Contact AFC for more specific information.
