BASF has introduced Basotect UL®, its sound-absorbing and heat-insulating melamine resin foam, particularly suitable for the insulation of airplane cabins. Basotect UL will meet the ever-rising requirements made in aircraft construction in terms of sound protection and weight reduction as it weighs only 6 grams per litre, making it 30% lighter than conventional Basotect and it complies with the stringent fire-protection standards stipulated by aviation authorities. It is not only much more flexible than materials such as polyimide foam, but the BASF foam also retains its flexibility, even at extremely low temperatures at which it exhibits a better thermal insulating effect.
Due to its filigree, three-dimensional network structure consisting of easily thermoformable filaments, panels made of Basotect UL are simpler to install than the glass fibre pads with which manufacturers normally insulate their aircraft. In a complex procedure, glass fibres have to be spun before they can be secured in the form of pads between the ribs of the airplane fuselage. Moreover, the vibrations that typically occur during flight cause the fibres to slip down over the course of time, which can impair the insulating effect. Basotect UL, in contrast, is more flexible and softer than glass fibres - so it is simple and quick to install while being permanently secured against slippage.
