Hydlar® Z is a Kevlar® fiber reinforced Nylon 6/6. With the addition of Kevlar®, Hydlar® Z's properties improve, better dimensional stability is achieved and wear resistance is increased ten times that of unfilled nylon. Hydlar® possesses a combination of physical properties that cannot be found in any other commercially available engineered plastic.

Hydlar® is applicable to a wide variety of industrial applications where high strength, extreme wear resistance and low abrasiveness are required. Typical applications would be wear strips, bearings, bushings, rollers, gears and wherever wear and abrasion resistant materials are required.

Typical Properties:

  • Extremely wear resistant
  • Superior abrasion resistance
  • Outstanding machinability
  • No galling or mating wear surfaces
  • Good dimensional stability


  • Bushings
  • Bearings
  • Rollers
  • Wear strips
  • Gears
