ISOPLAN high quality materials for thermal insulation



 Material profile

The raw materials used for the production of ISOPLAN are special ceramic and mineral fibres.

In combination with fillers and binders high temperature resistance results, and owing to low heat conductivity the insulation properties are very good.

The organic binders burn out between the temperature range of 300 to 400℃ and the ISOPLAN sheets will discolour during this precess. At high temperatures the discolouration disappears again.

 Applications

The very high temperature tolerance and the low theat conductivity values determine application material.

The following list shows typical examples for the wide range of applications:

  • Steel industry
  • Melting departments and foundries
  • Industrial furnace and boiler construction
  • Oil and gas burners
  • Hearth flaps, fire-resisting doors
  • Hot air insulations
  • Furnace and drying equipment
  • Engineering and equipment construction
  • Electrical equipment
  • Glass industry


Technical information about ISOPLAN


 Flat gaskets from ISOPLAN

The ISOPLAN grades have a well-balanced density and ared, therefora, suitable for both high-temperature insulation and sealing against inert gases up to an internal pressure of 3 bar.

When using ISOPLAN as a flat gasket it is necessary for reasons of safety and good functioning to make sure that the surface pressure in service does not exceed 10 N/㎟ and that the minimum gasket width is considered.

 Heat conductivity the criterion that matters!

 

In addition to the high temperature resistance heat conductivity is the decisive parameter for evaluating of an insulating material. Heat conductivity indicates that flow of heat (in Watts) through a material thickness of 1m and a surface area of 1㎡ with a 1 Kelvin temperature difference between the surfaces.

This is stated as : W/mk)

The lower this value, the better the insulation capacity of a material.

Changes in heat conductivity value can be seen from the diagram - they result from the test reports of Forschungsinstitut fuer Waermeschutz e. V., Muenchen (Research Institute for Heat Insulation e.V., Munich).

 Insulation diagram

 

From the curves of this diagram the required thickness of an insulation at defined temperatures at the "hot" face and the "cold" face of a plane surface can be seen.

The example marded shows a thickness of 8㎜ for ISOPLAN 1100 and of 10㎜ for ISOPLAN 750.
