Porsche Gets the Sound Right with BASF Foam
Basotect, a melamine resin foam from BASF, reportedly ensures the right sound effects under the hood of the Porsche Panamera Diesel. The foam is used for both sound and thermal insulation in the four-door Gran Turismo's engine compartment, transmission tunnel, and paneling near the engine. In addition to its good acoustic properties and high thermal resistance, the low weight of the foam is what especially attracted developers from the Stuttgart-based manufacturer. Basotect is used to absorb sound in vehicles wherever there are high operating temperatures over an extended period of time, such as in the separating walls between the engine compartment and the car interior, engine hood paneling, engine proximity shells, and transmission tunnels.
Basotect is especially well-known for its acoustic properties. Thanks to its open-cell, fine foam structure, it has very good sound absorption values in the medium and high frequency ranges. Drivers and passengers in the Panamera can therefore enjoy the typical Porsche engine sound - without annoying accompanying noise.
Jügen Ochs, Manager NVH Body (Noise, Vibration, Harshness) at Porsche, explained: "With its 184kW/250 HP six-cylinder diesel engine, the Panamera's engine compartment is regularly subjected to temperatures of up to 180 degrees. And Basotect withstands these extreme conditions."
