MICROPOROUS HIGH-PERFORMANCE THERMAL INSULATION FROM 190 °C TO 1100 °C

Nanotechnology is one of the keys to innovation

The highly efficient insulating effect of our products is based on a microporous fumed silica. Between the spherical microporous particles only punctual transition points occur. In this way, thermal conductivity by possible contact of solid particles is reduced to the largest possible extent. In addition, the created micropores also minimize thermal transmission by convection. Specially developed infrared opacifiers additionally reduce thermal transport processes by absorption and reflection of radiation.

In this way, it is possible to achieve much higher efficiency in comparison to conventional insulation materials like mineral fibers, lightweight refractory bricks or inorganic insulation panels.

For example, maintaining the same insulating capacity, the insulating material WDS® Ultra allows the reduction of layer thickness by the factor 6 and the weight can be reduced by a factor of 2 to 15. These already outstanding insulating properties can be further enhanced for certain applications by the use of vacuum technology. In this process, WDS® panels are fused into multi-layer barrier films, using a special patented process. The evacuation of the material completely prevents any thermal transmission by convection. Vacupor®-Vacuum insulation panels (VIP) produced in this way, reduce the overall thermal transmission to a quarter of its initial value.
