Nylon and UHMWPE.
Different compromises.
A strong fibre does not make every knot or application suitable.
| Question | Nylon | UHMWPE fibre |
|---|---|---|
| Stretch | Generally higher | Generally low |
| Termination | Use product-specific instructions | Slippery fibres often require specialised splices |
| Friction | Can damage any cordage | Heat tolerance needs particular care |
| Universal knot-retention value? | No | No |
| Working load from fibre name? | Cannot determine | Cannot determine |
Diameter, braid, coating, wear and bends all matter. Breaking strength is measured under specified conditions, not permission to lift that force. Knots can substantially reduce strength; the amount varies. This comparison cannot select climbing, rescue or suspension equipment.
