Comparison with other fibres

Dyneema® fibres have a unique combination of properties. With a density of only 0.97 the fibre floats on water. Its tenacity is the highest in the world and can be up to 15 times of steel. The modulus is very high and is second only to that of special carbon fibre grades. Elongation at break is very low, but due to the high tenacity, the energy to break is high.
