Kevlar® (KV) is a soft, flexible sleeving used to bundle and/or protect wires, hoses and wire harnesses from extreme environmental conditions. Kevlar is braided from aramid fibers and has a unique combination of durability, pliability and high tensile strength. Kevlar has excellent thermal stability permitting long-term use at temperatures up to 160° C/320° F without significant strength loss.

Splicing may occur during the production of this sleeving. Two or three lengths may create a full spool.
Continuous lengths are available in most sizes at an additional 10% surcharge. Please specify if you require continuous lengths.

What Makes Kevlar® So Strong?
There are many components that contribute to the strength of Kevlar, including the fact that Kevlar is a polymer containing aromatic and amide molecular groups. When the molten Kevlar is spun into fibers, the polymers have a crystalline arrangement, with the polymer chains oriented parallel to the fiber's axis. The amide groups are able to form hydrogen bonds between the polymer chains, which act like glue holding the separate polymer chains together. The most recent XANES images confirm that the aromatic components of Kevlar have a radial (spoke-like) orientation, which allows for a high degree of symmetry and order.

Kevlar® does NOT melt or support combustion. Short term exposures (several minutes) as high as 300° C/572° F can be tolerated. Kevlar® sleeving offers strength and durability, yet is relatively light in weight. It is mostly used in the fiber optic and electromechanical cable industries where high temperatures and durability are required of the protective sleeving.
