Tyvek[R] garments are composed of flash spun high density polyethylene which creates a unique, nonwoven material available only from DuPont[TM]. Tyvek[R] provides an ideal balance of protection, durability and comfort of any limited use fabric technology. Tyvek[R] fabric offers an inherent barrier to particles down to 1 micron in size. Protection is built into the fabric itself; there are no films or laminates to abrade or wear away.
