Racing Dyneema® 78 Runner has a Dyneema® SK78 12 strand coated core with a braided Kevlar® / Technora® / Polyester melange cover. This specially designed cover has been developed in conjunction with our rigging partners and is ideal for runner tails and high load sheets, especially where heat resistance and sheet control are important.
Elongation is based on figures taken from tests across the diameter range, to produce an average figure.
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.
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.
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.
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).
