Kevlar Rope

Novatec uses Dupont™ Kevlar yarns for high strength and fire resistant ropes including hot air balloon control lines. These aramid fibers boast 5x the strength of steel and unsurpassed lightness, flexibility and temperature resistance. Used in many high performance land and marine applications, Kevlar ropes from Novabraid range in braid type and diameter. Harsh environments like the deep ocean, high heat and even space don't make a difference when you choose this top quality, extraordinarily strong and durable rope.
