Refractory Sheet Type RSLE-501 is a low expansion high strength reinforced silica matrix composites in a cylindrical form. This remarkable material was designed for use as a high strength, durable insulator in induction heat treating applications. RSLE-501's very low thermal expansion coefficient, 0.3 x 10-6 °C, and high hot strength combine to give it thermal shock resistance not found in other structural ceramic materials. It provides remarkable resistance to the thermal shock up to 1200°C (2192°F) and beyond. RSLE-501 is non wetting with most non-ferrous metals.
ZIRCAR Refractory Composites, Inc. produces a comprehensive line of advanced high performance ceramic-ceramic composite materials and related products. Our materials are used around the world in the most demanding thermal, structural and electrical insulating applications ranging in temperatures from 600°C(1112°F) to 1650°C(3002°F). For over thirty years, we have been a problem-solver working with our customers to resolve their thermal management problems. We have developed products that have become industry standards for induction melting, forging and heat treating applications, investment casting, glass processing, hot pressing, as well as many high temperature electrical applications.
