Tyvek overalls are composed of flash spun high density polyethylene which creates a unique, nonwoven material available only from DuPont. Tyvek® provides an ideal balance of protection, durability and comfort of any limited use fabric technology. Dupont Tyvek overalls fabric offers an inherent barrier to small size particles. Protection is built into the fabric itself; there are no films or laminates to abrade or wear away. Tyvek overalls fabric's durability advantage over microporous film fabrics delivers consistently better barrier, even after wear and abrasion. Applications include: lead and asbestos abatement/remedation, general maintenance/operations, spray painting, general clean-up. Multiple interlocking threads are sewn around the raw edges of garment material to create a strong, stress-resistant seam
