We supply to the UK’s emergency services with many different types of products. DSM supplies many different products to the military services at home and abroad including:
Kevlar® fibres are produced by DuPont™, the fibres are extremely strong with a melting point is above 500°C (930 °F). Kevlar fibres also have a very good abrasion resistance making the fibre ideal as part of a technical rope cover.
Cordura® fibres are used in some of our ropes to provide extra grip, especially when handling the ropes for sheets or where additional holding power is required in Clutches and Jammers. Cordura® is a form of Nylon with a texturized finish.
Dyneema®, the world’s strongest fiber™, is respected as the premium brand for Ultra-High Molecular Weight Polyethylene (UHMwPE). We offer many ropes produced using Dyneema® fibres including single braids and double braids. We use Dyneema® SK99, Dyneema® SK78 and Dyneema® DM20 fibres to produce our ropes. These different types of Dyneema® fibre are used to produce ropes for specific applications.
Nylon (or Polyamide) fibres are stronger than Polyester fibres and provide greater stretch (elongation), Ropes produced with Nylon fibres can lose upto 15% strength when wet. The specific gravity of Nylon is 1.14 which makes it sink, the fibre has a melting point of 250 degree C.
Polyester has a specific gravity of 1.38 which means it will not float. Polyester has no strength loss when wet, it is flexible and has good abrasion resistance. Polyester fibres also have good resistance to chemicals and have a melting point of 295°C.
Rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called “tapping”. The latex then is refined into rubber that is ready for commercial processing.
Technora® is a para-aramid fibre, exclusively produced by Teijin Aramid in Matsuyama, Japan. The fibre is available in two colours natural beige colour and black version. Technora® is strong with excellent abrasion resistance, the fibre has no melting point but starts to decompose once the ambient temperature reaches 500 °C (932 °F).
