Not that I care, but since you asked.....

  • The filaments are bundles of polyester strands.
  • Each bundle of strands is encased in high-density polyurethane (PU HD).
  • Multiple bundles are used to construct the string itself, held together with PU HD.
  • Finally, it is coated with SPL (Silicium Pyrogene Lubritec)
