Unifrax Isofrax® 1260C Chopped Fiber Thermal Insulation
Categories: Ceramic; Oxide; Magnesium Oxide; Silicon Oxide

Material Notes: Isofrax® Thermal Insulation from Unifrax is a fiber that utilizes a unique, patented silica-magnesia chemistry to solve a variety of demanding, high-temperature application problems. Isofrax 1260C Fiber is the product of a long-term research and development effort by Unifrax to produce a fiber which has the high-temperature performance characteristics required in many applications at temperatures up to 1260°C/2300°F and also meets European and German regulatory requirements. Isofrax 1260C Fibers provide high-temperature stability, low thermal conductivity, low heat storage, thermal shock resistance, and low weight. Isofrax 1260C Fiber exhibits excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acids, phosphoric acid and strong alkalies. Isofrax 1260C Fiber also provides superior wetting resistance to molten aluminum alloys at high temperatures.

Isofrax 1260C Chopped Fiber was engineered to provide the vacuum former with a material which allows formation of complex shapes, a smooth surface finish and improved product details. These two grades of fiber have been developed to provide vacuum formers with an appropriate fiber for a wide range of finished product forms.

Applications: Isofrax 1260C Fiber is currently used in the manufacture of many high-temperature product forms such as felts, boards, papers, and vacuum cast shapes. This product can also be used as a high-temperature fill or packing material in a variety of applications, such as refractory expansion joints, furnace base seals, tube seals, and for packaging around burner tiles. Additional applications include reinforcement or fillers infriction materials and composites, and thixotropic agents in coatings and adhesives.
