With Prime-Light, Autoneum is launching a new technology for inner dashes and floor insulators that convinces with excellent shapeability, light weight and a high acoustic performance. Prime-Light will be presented to the public for the first time from June 23 to 24 at the International Automotive Acoustics Conference in Zurich, Switzerland. The renowned and traditional specialist vehicle acoustics event has been staged under the scientific leadership of Autoneum for more than 40 years.

Prime-Light is the latest further advancement of Autoneum’s successful Ultra-Light technology and represents a quantum leap in terms of innovation within the segment for inner dashes and floor insulators for vehicles. Compared with previous versions of Ultra-Light, Prime-Light components can be pressed into a wide variety of different shapes and sizes. This way they adjust optimally to the individual body-in-white shapes and take account of increasingly complex production processes in vehicle construction. Thus, Prime-Light can now also be applied in vehicle models where Autoneum’s Ultra-Light technology could not be used so far.

Prime-Light also convinces with a light weight while maintaining the same level of acoustic protection. Thanks to a thirty percent weight reduction compared with previous models, Prime-Light-based inner dashes and floor insulators save more than two kilos of weight in average. Automobile manufacturers and end consumers equally benefit from this weight reduction: If, for instance, the weight of a vehicle is reduced by 100 kilograms by means of lightweight materials, this leads to a 0.55-liter reduction per 100 kilometer driven in gasoline consumption and almost 13 grams fewer of CO₂ emissions (based on overall consumption of 5.5 liters per 100 kilometers in average).

Prime-Light-based inner dashes and floor insulators consist of thermoplastic cotton felt compounds in which the share of recycled materials amounts to up to 50 percent depending on the application-specific composition. In order to achieve the greatest possible acoustic protection, Autoneum already models and analyzes the ideal density and thickness of these components during the design phase of new vehicle models. Prime-Light will be produced in series for models of US OEMs in North America and China as of 2016.

Global bestseller
Prior to the market launch of Ultra-Light in 1998, insulations made of heavy layer foam were largely used in vehicle construction to curb noise. Autoneum introduced a pioneering paradigm shift with the launch of Ultra-Light: Since then, vehicle noise has not been merely insulated respectively quietened but absorbed. While sound-insulating components block noise and prevent it, for instance, from seeping through from the engine bay to the passenger compartment, sound-absorbing components “swallow” unwanted noise. The benefits of this paradigm shift are obvious: Products for the absorption of noise such as inner dashes and floor insulators are made of lightweight textile materials rather than heavy layer foam, thereby significantly reducing the vehicle weight. Autoneum produces around 19 million Ultra-Light components throughout the world each year for over 100 vehicle models of more than 20 car brands. Since its launch, over 160 million inner dashes and floor insulators as well as wheelhouse insulators have been produced on the basis of this technology, which was also honored with the renowned PACE Award.
