Braided polyester rope in white and black 1.5 mm to 12 mm

Polyester rope is a 16-carrier braided synthetic rope, available in white and black, in diameters from 1.5 to 12 mm. Polyester is one of the most durable and weather-resistant rope types: it's strong, UV-resistant, has minimal stretch and retains its strength in wet conditions. That makes it a go-to choice for applications where dimensional stability and a tight line matter.
The 8 mm variant is widely used for stretch tents, where a firm and stable rope is essential. All diameters are available per metre or on reels (100, 250 or 500 metres), available directly from stock.

Break strength per diameter
The values below are indicative for new, dry and knot-free polyester rope. A knot significantly reduces break strength.

Diameter Break strength Note
1.5 mm 40 kg
3 mm 150 kg
4 mm 405 kg Prorope measurement (see test block)
5 mm 410 kg
6 mm 575 kg
8 mm 1,037 kg Prorope measurement (see test block)
10 mm 1,540 kg
12 mm 2,160 kg

Note: the 8 mm value reflects the break strength actually measured by Prorope. All values are indicative and may vary in practice. We will be testing the full polyester range shortly.
