Durarope

Multifilament Braided Rope

Durarope is a new generation, high performance, light weight, multifilament braided rope.

Soft - easy to handle and store.
Excellent knot retention.
Not damaged by diesel fuel, petrol, battery acid, grease, or oil.
Unaffected by water - can be stored wet or dry.
Long lasting - with UV protection against sunlight degradation.
Resistant to fungus & mildew.

Durarope is made of 100% polypropylene Duralene yarns. These yarns are made from a polyolefin of non-polar nature comprising of high molecular paraffinic hydrocarbons; it has a very high chemical resistance compared to other synthetics. It is stable towards inorganic salts and to almost all inorganic acids and alkalis even at high concentrations and at temperatures above 60° centigrade.

The water absorption of Durarope is extremely low, both at room temperature and at 100° centigrade. The physical properties and dimensional stability of the yarns is independent of environmental humidity.

Durarope is available from 5mm to 20mm diameters.

Climbing ropes | edit

DURAROPE climbing ropes utilize a kernmantle construction consisting of a core (kern) covered by a sheath (mantle). The core is the main load-bearing element and largely determines a rope’s characteristics, such as static elongation, maximum impact force, and strength. The sheath is braided tightly around the core and its primary purpose is to protect the core against abrasion, but the relationship between the core and sheath also helps determine a rope’s handling characteristics.

Prior to World War II, all ropes were made of natural fibers, including jute, sisal, cotton, and manila. Today, all mountaineering and rappelling ropes are made of 100% nylon, or with a polypropylene core with a nylon sheath. Nylon offers the closest thing to an ideal combination of strength, resiliency, elasticity, and abrasion resistance, and is hence ideally suited for mountaineering use.
