Tyvek® is formed by a fully integrated process using continuous and very fine fibers of 100 percent high-density polyethylene that are randomly distributed and nondirectional. These fibers are first flash spun, then laid as a web on a moving bed before being bonded together by heat and pressure - without the use of binders, sizers or fillers. By varying both the lay-down speed and the bonding conditions, DuPont technicians can engineer the flashspun sheet to meet market needs, such as soft- and hard-structure Tyvek®.
