KEVLAR sewing thread with STEEL

Sewing thread KEVLAR with STEEL AISI 314 (1.4841) It has the same characteristics as the original Kevlar but also withstands temperatures up to 1000ºC and has great resistance to corrosion.

The KEVLAR sewing thread with STEEL is manufactured in two different ways:

Kevlar coated steel thread spun
KEVLAR SS 30 – NM 30/1 – Carton of 2.000m

Twisted steel wire with Kevlar filament
KEVLAR SS F10 – NM 8/2 – Carton of 600m
KEVLAR SS F8 – NM 8/3    – Carton of 500m
KEVLAR SS F6 – NM 8/4    – Carton of 400m

Other sizes available on request.

Also available with treatment:

– WR: Water-repellent and oil-repellent.
– SW: Semi-waxed
– WAX: Tarpaulin
– EXTRA-LUB: Extra-lubricated
– BONDED: Improves seamability and abrasion resistance.

Complies with regulations: EN 469, EN ISO 11611, EN ISO 11612, EN ISO 14116, EN ISO 15025, EN ISO 3146


The Kevlar® maintains its strength and resilience to almost the cryogenization point (-196ºC); in fact, it is slightly more resistant to low temperatures. At high temperatures the breaking strength is reduced by 10-20%, and after several hours of exposure the resistance is further reduced.

For example, at 160 ° C (320 ° F) and after 500 hours of exposure the temperature is reduced by 10%. At 260 ° C (500 ° F) and after 70 hours of exposure the resistance is reduced by 50%.

Like other polymers, Kevlar® is sensitive to prolonged exposures to ultraviolet (UV) rays with consequent surface degradation (yellow to brown). Although this degradation is only limited to the surface due to the self-reflective property of Kevlar®, UV exposures should be minimized during storage and handling, keeping Kevlar in light-resistant bags or boxes.
