ABSTRACT:
A fire-retardant air and water vapor permeable foam material resistant to passage therethrough of noxious chemicals in liquid or vapor form is described. The foam material is typically an open-cell polyurethane foam including a particulate adsorbent, organic binder and a solid water-insoluble fire-retardant dispersed in the foam. The foam material is bonded on at least one side to an air and water vapor permeable fabric to form a fire-retardant laminate material suitable for the manufacture of various protective garments.
