DuPont™ Tyvek® 400 SFR garments are lightweight, disposable secondary flame-resistant overgarments designed to help protect and preserve primary flame-resistant garments, while providing an ideal balance of protection, durability, and comfort.

Relaxed fit coverall design features a diamond gusset crotch to allow for unrestricted movement and optimal fit when wearing primary flame-resistant protective clothing beneath.

Composed of flash spun high density polyethylene breathable nonwoven Tyvek® fabric that has been flame-retardant treated, available only from DuPont, Tyvek® 400 SFR garments offer an inherent barrier against particles (down to 1.0 µm in size).

Tyvek® 400 SFR represents a new generation of disposable secondary flame-resistant garment technology. Compared to traditional disposable secondary flame-resistant garments that have been available for years, Tyvek® 400 SFR is a differentiated multi-hazard garment solution, offering superior particle barrier protection and improved durability in a lighter-weight fabric. This unique combination of performance allows Tyvek® 400 SFR garments to be worn over primary flame-resistant garments like Nomex® when hazardous particle and flash fire hazards exist. Additionally, Tyvek® 400 SFR is a more sustainable garment solution and can be recycled through the Tyvek® protective apparel recycling program if not contaminated with hazardous materials.
