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 60c° centigrade.
The water absorption of Durarope is extremely low, both at room temperature and at 100c° centigrade. The physical properties and dimensional stability of the yarns is independent of environmental humidity.
Durarope is available from 5mm to 20mm diameters in 2 different constructions Heavy Duty Braided and General Purpose Knitted Ropes.
High Performance Multifilament Braided Ropes
Durarope braided ropes are made from premium high tenacity polypropylene and nylon multifilament yarns. They are of braided construction giving a balanced non-rotating/non-kinking rope with excellent handling characteristics. All production steps such as core- and sheath-yarn twisting, plying, and braiding, and rope pre-tensioning and thermosetting are carefully monitored.
Ropes for Climbing and Mountaineering
All mountaineering and rappelling ropes are made of a polypropylene core with a nylon sheath, or 100% nylon. Nylon offers the closest combination of strength, resiliency, elasticity, and abrasion resistance that is ideal for mountaineering use.
Major Benefits
- High performance, well balanced properties
- Excellent abrasion resistance
- Kink free, no twist – can be easily coiled by left or right handed person
- Pliable – easy to handle and store
- Excellent knot retention
- Torque-free rope construction gives a non-rotating rope
- Stronger, more abrasion resistant and longer lasting than cotton, jute, manila or sisal ropes
Durarope climbing ropes are of 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 strength, static elongation, and maximum impact force. The sheath is braided tightly around the core and its primary purpose is to protect the core against abrasion. The relationship between the core and sheath also contribute to rope handling characteristics.
Dynamic Ropes
Ropes used for climbing are normally dynamic. These are designed to stretch upon loading, absorbing shock and dissipating the energy generated when arresting a fall. Dynamic ropes are of nylon, and where required the core is shrunk and stabilized by steam to increase the elongation under load and to reduce changes after becoming wet. Sizes range from 8 to 11 mm diameter.
Static Ropes
Static ropes have relatively less extensibility. When new, the elongation at 10% of breaking strength is approximately 5%. Static ropes are used for rescue work and other applications which do not require high energy absorption.
General Purpose Knitted Ropes
Durarope general purpose ropes are made from high tenacity multifilament polypropylene yarn of braided kernmantle construction, having the following advantages:
- Lightweight, floats on water
- Excellent wet/dry strength retention
- Kink free, no twist – can be easily coiled by left or right handed person
- Pliable – easy to handle and store
- Excellent knot retention
- Torque-free rope construction gives a non-rotating rope
- Stronger, more abrasion resistant and longer lasting than cotton, jute, manila or sisal ropes
- Colourfastness (with additional UV protection against sun light degradation)
- Unaffected by water – can be stored wet or dry
- Does not absorb water – dries faster
- Same strength and dimensional stability – wet or dry
- Resistant to fungus & mildew
- Stain resistant
- Unaffected by diesel fuel, petrol, battery acid grease, oil, etc.
