Unifrax Fiberfrax® LDS AL-Moldable Moldable Insulation
Categories:	Ceramic
Material Notes:	Fiberfrax LDS and LDS-AL moldables consist of Fiberfrax ceramic fibers dispersed in a sticky water-based refractory binder. These materials have a putty-like consistency which permits application by caulking, troweling, or hand forming. Both products adhere well to most surfaces. Drying is accomplished at a noncritical, elevated temperature, and the resulting dried material is strong, hard, and erosion resistant. LDS-AL moldable possesses excellent resistance to wetting by many nonferrous molten metals and is used extensively in molten aluminum contact applications. Typical Applications Lining for molten aluminum transfer troughs Lining for molten aluminum transfer ladles Information Provided by Unifrax I LLC
