Morgan Advanced Materials has further extended its range of porous materials with the launch of HalFoam, alongside the introduction of new grades within existing product lines.
Haldenwanger HalFoam is foaming technology which create a porous surface for aluminium oxide (alumina) and fused silica base materials and offer total porosities of up to 80%. HalFoam Alumina, ideal for use within kilns, performs at temperatures up to 1,700ºC, while HalFoam Fused Silica has demonstrated thermal insulation properties of between 500ºC and 1,000ºC.
Michael Rozumek, R&D director for the Haldenwanger products business at Morgan Advanced Materials explained: “Over the past two years, Morgan has made a considerable R&D investment into our porous materials portfolio. Our porous extruded products, with porosities ranging from five per cent up to around 40%, can be used in a multitude of high-temperature applications where thermal shock is of particular concern. The introduction of the HalFoam products further extends our capabilities, offering up to 80 per cent porosity and enhanced protection for surfaces in environments which experience rapid temperature change.”
