Formulau00e7u00e0q polyurethane foams with poly butylene terephthalate (PBT micropowder.The idealization of a polyurethane foam which comprises as a component of the formula the polymer poly butylene terephthalate or simply PBT micronized to a particle size of 35 to 200 mesh.According to the percentage description below: - the group of hydrocarbons (polyol) from 40% to 100%; the group of aromatic (isocyanate) from 15% to 70%; group of polymers (DOLI butylene terephthalate), PBT micropowder of 35 to 200 mesh of 1% to 50% - group of the organic metal (octoate) 0,01% 2 % - group of surfactants (silicon oxide) of 0.1% to 2% - the group of catalysts (tertiary amine) 0.1% to 2% - the group of chlorinated chloride (methylene) from 1% to 10%
