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 includes lead and asbestos abatement/remediation, general maintenance/operations, spray painting, general clean-up. Frocks provide body-length jacket design with front snap closures for easy donning and doffing. Frock extends to knee. Ideal for applications that do not require the full body coverage of a coverall. Laydown collar. Elastic opening for tighter fit at wrist.
