Claretex fabrics are 100-percent glass textiles that are texturized for maximum coverage and ease in processing. Fabrics are asbestos free and are available in many finishes and treatments while still offering the high-temperature resistance of glass textiles. FERRATEX 25 is a fabric woven with yarns that are plied from 100-percent glass yarn and fine 304 stainless steel wire. These wire-reinforced yarns add strength and serve as a heat sink. FERRATEX 25 conforms to HH-P-0031(SH) and is used for contact temperatures to 1200° F.
