CS85

CS85 is a Calcium Silica based High temperature board. This board was developed to be a high temperature replacement for asbestos Transite. It offers our highest strength and electrical resistance combined with minimal shrinkage for applications up to and exceeding 1800°F. Potential applications include platen press insulation, foundry core and blow plates, induction furnace casing, electrical resistance insulation, hot glass handling and numerous others.

CS85 Applications:

• Potential applications include platen press insulation, foundry core and blow plates, induction furnace casing, electrical resistance insulation and hot glass handling.

• Calcium silicate is non-corroding and will not disintegrate even after prolonged immersion in water. It is well suited for excessive moisture conditions where metal may suffer from severe corrosion and other insulations can become mushy and dissolve. As an extra precaution in conditions with excessively high moisture and thermal cycling (including freeze-thaw), BNZ suggests the use of oligomeric siloxanes, sodium silicates (water glass), or acrylic latex to help prolong the longevity of the insulation.

CS85 Typical Uses:

• industrial oven insulation, press platen insulation, glass manufacturing, kiln insulation, high temp insulation, induction furnaces, crucible insulation, molten aluminum insulation, bushings, washers, spacers, covers, tops.
