RB ceramic fiber blanket is high strength, needled insulating blanket that is made from RB bulk. The combination of long spun fibers and needling operation produce tough,resilient andstrong blankets,which resist tearing both before and after heating.RB blanket is completely inorganic and available in a variety of temperature grades,densities,and sizes.RB blanket can be folded,compressed and encapsulated to produce modules.
Bio-RB blanket is high strength, needled insulating blanket that is made from Bio-RB bulk. The combination of spinning and needling operation produce tough,resilient and strong blankets,which have superior thermal and mechanical properties. Bio-RB blanket is used in a wide range of applications including thermal insulation, appliances. Blanket can be folded, compressed and encapsulated to produce modules. It can meet European regulatory requirements (Directive 97/69/EC).
Features Typical Applications
Excellent thermal shock resistance Pipe wrap
Excellent thermal stability Furnace and kiln back-up insulation
High tensile strength Chimeny insulation
Low thermal conductivity Annealing furnace linings
Low heat storage Process heater linings
