UHMWPE staple fiber with crimped


1.21dtex/38mm,51mm,76mm, 1.91dtex/38mm, 51mm,76mm 60mm,76mm

Features & Benefits

  • High Strength:UHMWPE fibers possess high tensile strength, making them one of the strongest fibers available, even stronger than steel.
  • Very Lightweight:UHMWPE fibers are extremely lightweight, and even float in water.
  • High modulus:UHMWPE fibers have a high modulus of elasticity, providing excellent stiffness and dimensional stability.
  • Abrasion resistance:These fibers offer exceptional resistance to abrasion, ensuring durability and longevity in demanding applications.
  • Chemical resistance:UHMWPE fibers exhibit excellent resistance to chemicals, including acids and solvents, making them suitable for corrosive environments.
  • Low moisture absorption:UHMWPE fibers have low moisture absorption, allowing them to maintain their properties even in wet conditions.
  • UV resistance:UHMWPE fibers have inherent resistance to ultraviolet (UV) radiation, making them suitable for outdoor applications without significant degradation over time.
  • Good fatigue resistance:UHMWPE fibers show excellent resistance to fatigue, maintaining their performance under repeated loading cycles.


  • Spinning for technical yarns, yarns can be with higher tenacity to achieve better abrasion resistance
  • non-woven
