Click2Contact

The DuPont Tychem ThermoPro single-layer protective suit is designed for emergency responders and for at-risk personnel that deal with industrial chemical handling and remediation.

The suit provides triple hazard protection from liquid-chemical splash, flash fire and electric arc, combining the trusted chemical protection of Tychem and thermal/arc protection of Nomex into a single-layer garment. It provides at least 8 h breakthrough protection against 20 of the 21 standard ASTM F1001 chemicals and at least 30 min protection for more than 180 chemical challenges, including chemical warfare agents.

Taped seams offer strong chemical resistance against heavy liquid splashes, while a sewn seam is covered with a strip of compatible chemical-resistant material through heat sealing. The product also has an attached respirator-fit hood with a drawstring to pull tightly around a respirator and a longer zipper which extends to the chin for complete coverage of the neck area. It also has an elastic opening for a tighter fit around the wrists of the wearer.

The garment comes in either a bright orange colour for high visibility, or in grey, with or without attached sock boots.

The arc rating of Tychem ThermoPro fabric is 15 cal/cm² Ebt, exceeding the NFPA 70E Hazard Risk Category 2 requirement of 8 cal/cm².
