Material Notes:

ZIRCAR Refractory Sheet Type RSLE-57 is a low expansion high strength reinforced silica matrix composite . This material was designed for use as a high strength insulator in induction hot press applications w. RSLE-57`s very low thermal expansion coefficient and high hot strength combine to give it thermal shock resistance not found in other structural ceramic matrix composite materials.Information provided by ZIRCAR Refractory Composites, Inc.
