Polyamide combine tensile strength with breaking stretch, but swelling in the water, not resistance for some acids and UV radiation. But it´s very good weather-proof. The rope capacity, breaking stretch and dynamic absorption of load are high. Very good elongation at break: from 12% to 29%. This kind of rope is a good selection for all kinds of work, where used propelling force. So it´s use for shipping works, building, fire works, transportation and so on.
