WDS® Ultra is a microporous insulation material with an extremely low coefficient of thermal conductivity.
WDS® Ultra consists of inorganic silicates. The main constituent is fumed silica, the other components are opacifiers for minimising infrared radiation.
As can be seen in the graph below, thermal conductivity of WDS® Ultra is up to 5 times more effective than that of Ceramic Fibre.
Tried and tested applications for WDS® Ultra include insulation for heat-treatment furnaces in the aluminum industry, or back-up insulation in the industrial furnace industry.
WDS® Ultra fulfills several functions, such as:
- Precisely controlled energy emission
- Reduction of weight and volume
- Increase of heat retention
- Increased effective volume
