Abstract
In an escape device for an aircraft having a pair of air bags formed of sheet members and a slide surface, the sheet members have a high tear strength and excellent flame retardancy. The sheet members forming the air bags are a rubber covered fabric having a substrate of fabric and covering layers of a thermosetting elastomer which contains a flame retardant. By using a flame retardant in the form of needle-like crystals having a high aspect ratio and a small crystal grain diameter, the flame retardant will not aggregate in the elastomer, but will be uniformly dispersed, so that the bond strength between the substrate and the covering layer is high.
