Dyneema SK78 cord with polyester sheath – 2 to 5 mm

Dyneema SK78 is a high-performance braided core/sheath cord that combines extreme strength with a minimum elongation of less than 1%. The core consists of SK78 fibres — one of the strongest synthetic fibres in the world — protected by a braided polyester sheath. This makes the cord not only exceptionally strong, but also flexible and comfortable to handle.

Advantages of Dyneema SK78
Less than 1% elongation – dimensionally stable and reliable, even under load
Very high break strength – at 3 mm our own test lab measures a break strength of 526 kg
Braided polyester sheath – protects the Dyneema core and provides a smooth, comfortable grip
Abrasion-resistant and durable – built for intensive use and weather exposure
Compact and lightweight – significantly thinner than traditional rope types at equivalent strength

Available diameters

The Dyneema SK78 cord is available in diameters from 2 to 5 mm, held in stock as standard. Also available on a convenient spool, and custom orders (length, diameter or colour) are possible on request.

Applications

Thanks to the combination of strength, low elongation and a flexible sheath, this cord is widely used for:

Sun awnings and patio covers
Pull cords and tensioning systems
Applications requiring a thin, strong and dimensionally stable cord
