SILICA-MAGNESIA, NON-RCF PAPER TYPE RSPA-SOL 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). Uses Include:
Physical Properties and Charicteristics of RSPA-SOL
*Maximum use temperature is dependent on variables such as stresses, both
thermal and mechanical, and the chemical environment that the material
experiences. Insulating Value of RSPA-SOL The following table summarizes the insulating characteristics of RSPA-SOL Paper.
ZRCI Silica-Magnesia Papers Type RSPA-SOL according to directive 97/69/ec, posses a fibre chemistry within the regulatory definition of a "man-made vitreous (silicate) fibre with random orientation with alkaline oxide and alkaline earth oxide content greater than 18% by weight." These fibres have been tested pursuant to EU protocol ECB/TM/26,Revision 7, Nota Q, Directive 97/69/EC, with results that are below regulatory thresholds. As a result, these papers do not require additional labeling or further testing. In addition, Intratracheal Instillation Biopersistance Testing per the German Hazardous Substance Ordinance has been conducted on these fibres with results that are below German regulatory thresholds. Refer to the product Material Safety Data Sheet (MSDS) for recommended work practices and other product safety information. AVAILABILITY
