Unifrax Isofrax® 1260C Paper Fiber
Categories: Ceramic; Oxide; Magnesium Oxide; Silicon Oxide

Material Notes: Isofrax® 1260C Paper is manufactured by forming Isofrax 1260C Fiber in a nonwoven matrix. The fibers are randomly oriented during manufacture, then held in place with a latex binder system. A specialized, statistically controlled paper-making process is utilized to form uniform, lightweight, flexible materials, including Isofrax 1260C Paper.

Isofrax 1260C Fiber, the fiber utilized in Isofrax 1260C Paper, utilizes a unique, patented silica-magnesia chemistry to solve a variety of demanding, high-temperature applications 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 regulatory requirements (Directive 97/69/EC).

Isopaper 1260C Paper exhibits excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis. Isofrax 1260C Paper also provides superior wetting resistance to molten aluminum alloys at high temperatures.

Isofrax 1260C Paper will generate small amounts of smoke and trace element outgassing during initial exposeure to temperatures above 230°C (446°F).
