FBX 1900 Block is composed of high temperature mineral fibers bonded together with a special combination of organic and inorganic binders. It is recommended for use in applications requiring a high temperature rating and /or greater residual strength than available in organic bonded board insulations. Its low rate of moisture absorption allows placement of castable refractories in direct contact without degradation. Typical uses of FBX 1900 Block includes direct or refractory back-up installation in ovens, furnaces, kilns, power generation equipment and a wide variety of process equipment. FBX 1900 block is easily impaled with a knife or saw to fit irregular surfaces.
Service: Recommended for continuous service at temperatures up to 1900 ºF. Melt point exceeds 2000 ºF.
