Durability

Dyneema® fibres are produced from polyethylene and do not contain any aromatic rings, nor any amide, hydroxylic or other chemical groups that are susceptible to attack by aggressive agents. The result is a highly crystalline fibre with excellent resistance to water, moisture, most chemicals, UV light and micro-organisms. Dyneema® fibres do not swell or hydrolyse in water, sea water or moisture.
