| titleOfInvention |
Process for preparing polyurethane foams |
| abstract |
The invention relates to a process for the production of semi-hard and hard polyurethane foams by reacting organic polyisocyanates with neutral, acidic or basic salts of hydroxyl-containing secondary and / or tertiary amines and naphthenic acids and optionally conventional polyols in the presence of blowing agents and optionally catalysts, auxiliaries. and additives.n n n The polyurethane foams produced according to the invention have a density of 15 to 150 g / l. The semi-hard foams are characterized by their high toughness, low brittleness and good flow properties. The hard foams have excellent compressive strengths. |
