Tyvek 400 garments are composed of flash spun high density polyethylene which creates a unique, nonwoven material available only from DuPont. Tyvek 400 provides n 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, general clean-up.
