V-19 Block has a nominal density of 24 lb/ft3 (0.38 g/cm3) and an average compressive strength of 134 psi. It does not contain organic binders or fillers. Every dimension is cut to size, and tolerances are a max I 0.062 in. (I1.5 mm). It is available in standard 36 in. x 12 in. (915 x 305 mm) size block and thickness increments of 1, 1.5, 2, 3 and 4 in. The block must be predrilled for placement since it is not impalable over anchors due to its green strength. This property makes it a suitable base on which to cast or gun refractory castables and also allows using it in all types of furnace lining constructions with firebrick, refractory plastic and ceramic fiber materials.
