High-temperature refractory paper RSPA-SOL

thermal insulationfor furnaces

ZRCI Silica-Magnesia Papers Type RSPA-SOL are thermal insulation products capable of withstanding continuous operating temperatures up to 1260°C (2300°F). Type RSPA-SOL papers are designed to have enhanced in-vitro solubility characteristics which enable them to meet European regulatory requirements for synthetic vitreous fibers (European regulatory requirements directive 97/69/EC). These unique papers exhibit excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalis. Type RSPA-SOL papers also provide superior wetting resistance to molten aluminum alloys at high temperatures. Type RSPA-SOL papers will generate small amounts of smoke and trace element outgassing during initial exposure to temperatures above 230ºC (446ºF). Insulating Value of RSPA-SOL The following table summarizes the insulating characteristics of RSPA-SOL Paper. Composition Instructions Uses Include: Annealing Cover Seals. Investment Casting Mold Wrap. Expansion Joint Seals. Nuclear Insulation Applications. Useful When Refractory Ceramic Fiber Are Not Desired. Thermal Reactor Insulation. Soaking Pit Seals.
