Aluminized rayon, available in both 15- and 19 oz. / sq. yd. weights, is well known as a comfortable, yet effective, fabric for aluminized protective clothing. It is very flexible and lightweight, which reduces heat stress and fatigue, and enhances the wearer's comfort. Aluminized rayon displays excellent radiant heat, molten aluminum, and iron splash protection according to the EN 531 standard (which has been superseded by the ISO EN 16112), and the ASTM F955 test. This fabric is one of the more economical options available for manufacturing aluminized protective clothing.
