HYDLAR Z - aramid (Kevlar®) fiber filled

HYDLAR™ possesses a combination of physical properties that cannot be found in any other commercially available engineered plastic. Design engineers have created a family of superior wear and abrasion resistant thermoplastics using aramid fiber reinforcement.

  • High Strength Rods and Plates
  • Extremely Wear Resistant
  • Increased Surface Temperature Capability
  • Highly Resistant to Abrasion
  • No Galling of Mating Wear Surfaces
  • Good Dimensional Stability
  • Outstanding Machinability

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.
