Materials

PURPolyutheranes are usually soft, opened-cell, and with great noise absorption properties. There are two great families: the ones based on ether, water-proof, whereas the others are based on ester, oil-resistant. Additives and impregnations can also be added to provide it with higher resistance to fire or dampness. Alternatively, reticulation processes can create filtration foams bearing porousness between 10 and 80 ppi. The main function of this family of materials is to absorb noises and vibrations and to avoid air flow when they are compressed, without effort when they have to be adapted to the right place. They can also act as liquid filters and as packaging and protective material.
