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)
