Kevlar Cord with Polyester Sheath | 1.5 to 4 mm

Description

Kevlar cord with polyester sheath combines the extreme tensile strength of aramid with the abrasion resistance of a braided polyester outer sheath. The aramid core delivers minimal stretch and high break strength, while the sheath protects the core against chafing and UV radiation. Available in 1.5, 2, 3 and 4 mm, orderable per metre.

Properties of kevlar cord with polyester sheath

-Aramid core with minimal stretch under load

-Protective polyester sheath against abrasion and UV

-Heat resistant

-Does not rot and absorbs virtually no moisture

-Custom cut, available per metre

Break strength of kevlar cord per diameter

The values below are not taken from the manufacturer's datasheet, but measured on our own 50 kN tensile tester — five pull tests per rope, in accordance with ISO 2307:2019.

Diameter	Break strength	Application	Test
1.5 mm	107 kg	Mini cranes, model building, precision lifting	Test database
2 mm	117 kg	Guy lines, suspension systems	View test
3 mm black	220 kg	Heavy-duty suspension, industrial	View test
3 mm neon yellow	162 kg	Visibility, signalling	View test
4 mm	302 kg	Lifting applications, construction	Test database

Which diameter kevlar cord do you need?

Choose diameter based on load, not gut feeling. As a rule of thumb, use a safety factor of 5 for static use and 10 for dynamic or shock loads. Also keep in mind that a knot significantly reduces break strength. Not sure? Email info@prorope.com — we're happy to help you figure it out.

Looking for maximum strength and UV isn't a factor? Pure kevlar 3 mm hits 596 kg — nearly three times as much as the same diameter with a sheath.
