Cord 4 mm.
Outside jacket: Red-black braided high tensile strength low stretch polyester (NO high stretch polypropylene used!).
Core: Aramide 2000 superstrong no-stretch fiber.
Extremely souple and rapid to use. No stretch because of the Aramide 2000 fiber in the core.
Aramide is one of the modern superstrong fibers like Kevlar, Vectran, Dyneema and Twaron. Aramide only can be cut with a very sharp knife. It cannot be melted.
Attention: The end of the cord can be finished by melting the outside polyester jacket and then rolling the melted material between a wetted thumb and index.
The very thin white cord below the red black cord already withstands 125 kg before breaking. It could tension a djembé on itself ! The red-black cord that we sell (see picture) contains three times this quantity of superstrong and stretchless fibers. To this strength you may add the jacket of low stretch polyester (no high stretch polypropylene is used which is much cheaper and may look the same as polyester) ! Our cord was specially developed to fit on or repair traditional African drums in a professional way !

General info on cord materials:
Cord can be manufactured in many different ways and with many different fabrics and combinations between these. Common fabrics are:
A nylon cord stretches a lot before breaking. UV light will harden the nylon.
Polypropylene stretches even more than nylon. It is cheap but the quality is corresponding because it features also a lot of wear. The cord floats on water.
A Polyester cord is more expensive, but resists wear good. It stretches a lot less than nylon or polypropylene.
For low stretch applications the cord can be pre-stretched. For more serious applications a core of dyneema, aramide, spectra, vectran or PBO can be used. By using polyester as the sheath protecting the core against wear and UV light a perfect no-stretch combination is obtained. During production special attention has to be paid to making a very tight sheath.
Dyneema is similar to Spectra. Can be melted easily, floats on water and has extremely low stretch. It was invented by DSM (Dutch State Mines), while Spectra is manufactured by Honeywell.
Aramide (also known under the name Kevlar (Trade mark of Dupont) and Twaron (Teijin company formerly the Dutch AKZO). Aramide shows very low stretch and a high breaking force. Fibres do not melt.
Vectran has the same (yellowish) colour as aramide, but has a still higher breaking force.
PBO is the most modern fibre in this line-up. Very low stretch, no creep (stretch at long term). Very sensitive for UV light ! Already under a TL light it lost 50% of strength in 24 hours. So the line should never be used without an outer jacket of polyester.
Attention: Numbers are purely for indication.
* No data available but comparable to vectran and dyneema.
