Strong traditional weave webbing with IRR SPECFlat nylon webbing is great for high abrasion and strength applications.It is ideally suited for leashes, straps, D-ring belts, etc. NB: Nylon stretches when wet, so a nylon strap will not stay tight in the rain or with marine applications.Use with 25mm buckles.Nylon is a versatile fibre often specified for military webbing and is suitable for many other uses.Nylon was the first commercially available synthetic fibre.The strength is high tenacity (Up to 9g/den).Elongation - approximately 20% at break - more when wet . This means that nylon webbing will extend when put under tension outside.Abrasion - nylon has very good abrasion resistance.Moisture - has a regain of 4-5 % and feels damp quicklyTemperature - the melting point is around 250 degrees C and is able to withstand 150 degrees C for many hours (It will discolour). Nylon can cope with low temperature very well (-80 Degrees C with no loss of strength).Nylon is difficult to ignite and tightly woven structures do not burn quickly.Excellent resistance to sunlight.Good chemical resistance to dilute acids, decomposes in strong acids. Good resistance to common alkalis.
