BNZ manufactures a variety of non-asbestos calcium silicate structural insulations that combine high strength and excellent thermal insulating characteristics for use in a variety of heat processing, fire protection and electrical resistance applications. Our Tobermorite crystalline structure provides excellent thermal shock resistance as evidenced in its typical use as a direct contact board for non-ferrous metals and in fire training burn rooms. It is fire resistant to temperatures approaching 2000°F. The Tobermorite crystal is also unique by providing low thermal conductivities that remain relatively constant over a broad range of operating temperatures.

Description

BNZ structural insulations are monolithic, incombustible and non-asbestos. They are available in thicknesses ranging from 0.25" to 3" and are easily fabricated from 4'x8' sheets. The diverse selection of boards are produced by chemically reacting formulations of silica, lime and reinforcing fibers followed by hydraulic pressure and various forms of curing and heat treating to create the insulation that is best suited for a particular application. The resulting Tobermorite crystal provides many advantages.

  • Thermal shock resistance and stability
  • Consistently low thermal conductivity
  • High structural strength at elevated temperatures
  • Incombustible
  • Electrical, insulating properties when dry
  • Easily machinable
  • Insoluble in water and non-corroding
