PORET - Ester and Ether Foams
Our many years of experience in the filtration technology sector provide the basis for our expertise in the field of foam filter. We offer a broad range of open-cell and closed-cell polyurethane foams in various colours and in all common densities. A special process known as reticulation is used after fabrication to open the pores of the foam. Various reactor configurations are available for fabrication of uniform open-cell pore structures with controlled pore spacings of between PPI 10 and PPI 80 (PPI = Pores per Inch).
Our foams are available in a wide range of sizes, shapes and colours in accordance with your specific requirements. They are available as bun stock, slabs, rolled sheet, cut-to-size sections, punched or moulded parts, etc.
Our PORET® product family comprises two principal filter foam materials:
These two types of foams differ in their hydrolysis resistance. Polyester foams are limited to applications which do not involve contact with water.
Polyether foams on the other hand are much more resistant to hydrolysis and other forms of chemical or environmental attack. Accordingly our polyether foam products are used with great success in fish keeping and biological water treatment applications.
