STEDAIR® 4000

STEDAIR® 4000 is a tri-component moisture barrier that provides protection for firefighting operations.  STEDAIR® 4000 combines a woven DuPont™ Nomex® pajama check substrate with an enhanced bi-component membrane. This bi-component membrane is comprised of expanded PTFE (Teflon) matrix that has continuous hydrophilic (water-loving) and oleophobic (oil-hating) polymer coatings impregnated into the fabric for liquid and chemical protection.
