High Temperature Insulation Thermal Conductivity

Although some non oxide ceramic fibers such as sic and c etc show higher thermal stability and infrared extinction coefficient than oxide ceramic fibers their high thermal conductivity the thermal conductivity of sic is 490 w m 1 k 1 and c is 800 w m 1 k 1 restrict their usage as thermal insulation materials.

High temperature insulation thermal conductivity. High temperature insulation wool is an ultra lightweight insulation material that due to its properties provides highly efficient thermal insulation for industrial furnace construction applications. Perlite insulation thermal conductivity of perlite insulation temperature and k values. High and fine porosity leads to low thermal conductivity. Fibre board and shape high temperature high performance insulation.

Ranges are marked with. In particular for the construction of industrial furnaces dryers and apparatuses but also in the cement and petrochemicals industries it is the classical cost efficient insulating material. Rath has been manufacturing products such as wool mats stampings and modules for more than 25 years now. High temperature wool can therefore be used to build very energy efficient periodically operated systems that can be heated and cooled quickly.

Our high temperature insulating fibre blankets provide thermal insulation in processing of metals petrochemicals cement ceramics and glass and are used by manufacturers of equipment for aerospace automotive marine and domestic applications. All high temperature insulation wools shrink at high temperatures. Various insulation material thermal conductivity chart. Insulation material thermal conductivity chart.

These insulation materials have a porosity 45. Correspondingly materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. R values per inch given in si and imperial units typical values are approximations based on the average of available results. We dedicate a complete page on thermal conductivity later work is in progress.

Chimney and duct insulation in power generation plants. Mineral wool insulation thermal conductivity temperature and k values. In short traditional single phase ceramic fibers can t meet the requirements of high temperature insulation materials for high thermal stability and low thermal. These fibre boards and shapes are mechanically strong and dimensionally stable up to 1649 c 3000 f.

For instance metals typically have high thermal conductivity and are very efficient at conducting heat while the opposite is true for insulating materials like styrofoam. Nr 1000 calcium silicate board is white and hard high temperature thermal insulation material based on lightweight calcium silicate with high strength low thermal conductivity lightweight pressure resistant character it can be used at most different areas of industry as backup insulation. Piping recommended insulation thickness recommended insulation thickness of heating systems like hot water low medium or high pressure steam systems. High temperature wools are characterized by low thermal conductivity low bulk density and low heat capacity.
