Kevlar, scientific name of Poly-paraphenylene terephthalamide, is a brand name of an aramid fiber produced by Dupont. Kevlar works normally in temperatures ranging from -196℃ to 204℃ for long periods of time, with a shrinking percentage of 0 at 150℃, and it will not decompose or melt at temperatures as high as 560℃. Kevlar's braided sleeving features an outstanding wear, moisture, puncture, corrosion and thermal resistance. It also features a high tensile force, light weight, high strength and stable size, so that it is suitable for the protection of wires and tubes even in severe environments.
