Rope Specifications

Double Braid Nylon

Nylon

Synthetic Fiber
Nylon 6 melts at 218°C
Nylon 6.6 melts at 258°C
UV Resistance: Good

  • Resistant to weak acids
  • Degraded by concentrated, strong acids
  • Unaffected by most alkalis at room temperature
  • Resistant to organic solvents, soluble in phenols and formic acid
  • Good strength
  • Excellent microbial resistance
  • Susceptible to creep (gradual elongation under load)
  • Abrasion resistance of wet nylon is generally poor
  • Minor loss of strength when wet; strength is re-gained once rope dries
