Ceramic Foam Insulation

Product ID:  1aa2
  

Ceramic foam insulation features its low density, high-strength and excellent thermal shock resistance, playing an important role in high temperature insulating. Being ceramic fiber free, ceramic foam insulation product is a great substitute to Aluminosilicate, Mullite and Alumina Ceramic Fiber. The main specifications of ceramic foam insulation are as following:

The advantages of Ceramic Foam High Temperature Insulation include:
  • Free of ceramic fiber and organic binder.
  • High application temperature from up to 1750 °C.
  • Higher strength than refractory ceramic fiber and lightweight ceramic brick.
  • Ultra-low density: 0.2-0.5 g/cm3
  • Low Thermal Conductivity and Linear Thermal expansion coefficient.
  • Great Thermal Shock Resistance.
  • Easily machined by CNC.
  • Safe and rapid maintenance.
 
 
 
Example applications of ceramic foam insulation are:
  • 1000-1750°C laboratory or industrial furnace lining.
  • SiC or MoSi2 heated furnace lining.
  • Furnace, kiln and oven hot face lining.
  • Kiln furniture and light kiln cars.
  • High temperature application with H2, CO or other reducing / oxidizing atmosphere.
