The primary patent for flexible polyurethane foam preparation was received by Zaunbrecher and Barth in 1942. The adaptable polyurethane foam was produced through simultaneous polyurethane synthesis and fuel technology by combining organic and natural toluene diisocyanate (TDI), aliphatic polyester, drinking water, and catalyst. With this just one-phase method, polyurethane was fashioned via the reaction in the isocyanates with the hydroxyl-useful groups from your polyester, whilst its gas phase was shaped with the technology of carbon dioxide.
