J-M S'lPEREX block Insulation | DESCRIPTION: J-M Superex block insula- ADVANTAGES lation is composed of calcined diatomaceous silica blended with other insulating materials and bonded High Compressive with asbestos fiber. These light weight, large size Strength tl blocks will withstand temperatures up to 1900F Compresses only V6" (2" thickness) under a pressure with negligible shrinkage. Their unique combina of 85 lbs per square inch. tion of low conductivity and high stability at ele vated temperatures provide excellent efficiency and long, maintenance-free service. Low Conductivity at High Temperatures Ever since its introduction, Superex has demon strated its versatility as a high temperature insula tion. Today, for example, it economically insulates 90% of this country's hot blast stoves. Superex has a conductivity of .82 at 1000F mean temperature. Low Heat Shrinkage Has a linear shrinkage of only 2.7% at 1900F. 10 | AVAILABLE FORMS:Furnished in fiat or curved blocks in the following sizes: Flat or curved, 3" or 6" wide by 18" or 36" long. Flat only, 9" or 12" wide by 18" or 36" long. Thicknesses ?ange from 1" to 4". | USES: Superex blocks are widely used for equipment operating at temperatures to 1900F in cluding boiler furnaces, hot blast stoves, mains and bustle pipes, hot gas flues, soaking pits, petroleum cracking furnaces, producer gas mains, and metal lurgical furnaces of various types. Dimensional Uniformity Straight, true edges and close tolerances make possible snug joints. Light Weight Ideal for insulating movable high temperature equip ment. Large Size Blocks Large 12" x 36" blocks speed application and reduce the number of joints. ET-000043 8Bl
