The present invention relates to an open-cell polyurethane foam comprising polyester and polyether structures and having a density of 70 to 300 g/L, 1 to 20 cells/cm, a rebound intensity greater than 30%, an elongation at break of greater than 200%, a tear propagation resistance of greater than 1.2 N/mm and a tensile strength of greater than 200 kPa. The present invention further relates to a process for producing inventive open-cell polyurethane sponges and to the use thereof as a pipe cleaning sponge.
摘要:
The present invention relates to a highly elastic flexible polyurethane foam obtainable by mixing a) polyisocyanate with b) at least one relatively high molecular weight compound having at least two reactive hydrogen atoms, c) hyperbranched polyester c1) of the AxBy type, where x is at least 1.1 and y is at least 2.1, and/or hyperbranched poly-carbonate c2), d) if appropriate, low molecular weight chain extender and/or crosslinker, e) catalyst, f) blowing agent and g) if appropriate other additives. The present invention further relates to a process for producing such a flexible polyurethane foam and the use of the flexible polyurethane foam of the invention for producing furniture, mattresses, orthopedic products, car seats and other upholstery in the automobile sector.
