Tychem® 4000, utilizes Saranex™ 23-P film laminated to Tyvek® fabric to provide a rugged and durable fabric that resists abrasion. Tychem® 4000 fabric provides at least 30 minutes of protection against >124 chemical challenges. Typical applications include chemical mixing, hazardous remediation, emergency medical response, paint spraying, and nuclear environments. Taped seams provide strong chemical resistance against heavy liquid splashes. A sewn seam is covered with a strip of compatible chemical-resistant material through heat sealing. Attached respirator-fit hood features elastic around face opening, which is designed to cover neck and chin and to fit around a respirator face mask. Coveralls also feature a strong zipper for tough, flexible closure. Storm flap covers zipper, which can be sealed by the wearer with adhesive strip to prevent intrusion at zipper. Elastic openings at wrists allows for a tighter fit. Integrated socks are composed of the same garment material. Attached flaps are designed to cover boot tops to help reduce potential for liquid intrusion.
