RegiCell reticulated polyurethane matrix foams for ceramic molten metal filters (7–50 ppi)
Country: · Model: RegiCell
Reticulated polyurethane foams with pore sizes from 7 to 50 ppi, from which ceramic foam filters for casting cast iron, stainless steel and aluminium are made. The uniformity of the cells directly determines filter quality. The foam is also used as a carrier in catalysts and battery electrodes.

Description
The open-cell foam is impregnated with ceramic slurry, the excess is removed, and during firing the polymer burns out and leaves a ceramic skeleton that exactly repeats the foam structure. For this reason pore size, cell uniformity and foam strength determine how well the filter cleans the melt of non-metallic inclusions and evens out the flow in the gating system. Net density of most grades is 27–30 kg/m³, compression load 3.8–4.7 kPa, tensile strength over 90–120 kPa, elongation at break over 80–120 %. Besides foundry use, the foam is used in liquid and gas filters.
How to choose
The grade is selected by metal and the fineness needed of the filter. RegiCell 7 FM 2 (7 ppi, net density 7 kg/m³) goes into filters for stainless steel, and RegiCell 8, 10 and 13 FM 2 into cast iron ones. Grades 15, 20, 25 and 30 FM 4 are used for aluminium and cast iron filters, and 40 GA and 50 GA for the finest pores. The higher the ppi, the finer the porosity. For filtering liquids and gases there are also the foams Bulpren and Filtren.

FAQ
Why is RegiCell foam used in making ceramic filters?
It serves as a matrix. The foam is impregnated with slurry and fired, the polymer burns out, and the ceramic skeleton repeats its structure.
What pore size is available in RegiCell foam?
From 7 to 50 ppi. Grades RegiCell 7 FM 2 and RegiCell 50 GA lie at the ends of the range.
Which foam grade suits filters for aluminium?
According to the manufacturer, RegiCell 15, 20, 25 and 30 FM 4 are intended for aluminium and cast iron filters.
What density and strength does RegiCell foam have?
Net density of most grades is 27–30 kg/m³, tensile strength over 90–120 kPa, elongation over 80–120 %.
