Plicast® LWI® 24 is the workhorse of Plibrico’s insulating refractory castables.   A service limit of 2450°F, moderate density, and adequate strength, make this material suitable for use as either as an efficient backup insulating component, or a primary lining material in less demanding, moderate temperature applications.   Product advantages include:

  • Good strength
  • 2450°F service limit
  • Medium density ~80 pcf
  • Moderately low thermal conductivity
  • Good volume stability
  • Good casting consistency
  • Good product storage life: 12 mo

This conventional dry mix castable is ideal for reheat, car bottom and bottom annealing furnaces (as backup insulation), boilers, incinerators and thermal oxidizers, aluminum furnaces (upper wall and backup insulation) mineral processing kilns (backup insulation). Can also be used as a back up product for an outdoor pizza oven (insulation under the hearth, or over the dome).
