We use polyurethane foams to develop and produce acoustic components. Polyurethane is the polymer that is best shaped into many different formulations with different properties, in order to achieve the desired performance. The mechanical performance of the foam, density, cell structure, cell opening, Young Modulus, compression resistance, are properties that offer acoustic comfort. We select and mix Polyol, Isocyanate, Catalysts, Accelerators and Additives to create the right foam that meets the required properties.
We also develop and use polyurethane as a matrix in structures of light composite, as well as polymeric films.
Fibres are the most used raw materials in our business.
We use fibres to create carpets, headliners, and other products. The fibres selected impart the required performance to the component, as well as to the optics and haptics of the overall interior of the vehicle.
All fibres, natural and recycled, are the raw materials required in designing acoustic components. The type of fibres, their diameter, length, elastic modulus, combined with the processes we implement, yield the acoustic properties desired.
We use very high performance fibres, such as carbon fibres, aramidic fibres and glass to produce composites. Mechanical performance, lighter weight, passenger safety improvement and an assembly modular approach are the key reasons for using these materials.
Thermoplastic Polymers and Compounds
In the acoustic components application, there is one area, sound insulation, where we develop and produce thermoplastic polymer blends and compounds.
Our self-developed and produced formulations and blends allow us to design and produce solutions that are dedicated to a specific acoustic need in a specific component. With our know-how, we are able to offer our customers the best combination in performance/weight ratio and cost.
The classical definition of a composite is that of a “matrix” with reinforcement fibres added to increase the stiffness/strength of the matrix itself. Our present technology is based on carbon fibres (or others) embedded into a polymeric matrix, thermosetting or thermoplastics, allowing us to have a high performance/weight ratio for our products, with potential integration of many parts or functions, achieving a «defect free» clear coat carbon look or painted solutions and very complex geometries with variable thicknesses.
