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.

| 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.
