Tyvek® 400 garments are composed of flash-spun high-density polyethylene, which creates a unique, nonwoven material available only from DuPont. Tyvek® 400 provides an ideal balance of protection, durability, and comfort of any limited-use fabric technology. Tyvek® 400 fabric offers an inherent barrier against particles (down to 1.0 micron in size). Protection is built into the fabric itself; there are no films or laminates to abrade or wear away. Tyvek® 400 fabric's durability advantage over microporous film fabrics delivers consistently better barrier, even after wear and abrasion. Applications include lead and asbestos abatement/remediation, general maintenance/operations, spray painting, and general clean-up.
