Using the one-shot process, the POLYTEC In-moulded Sound Absorber (PISA), which is made from acoustic absorber foam, is pressed simultaneously into an underbody. With its outstanding acoustic absorption capacity this ensures quiet in both the interior and exterior sections of the vehicle. In addition, the sealed sound absorber resists water, fuel, oil and brake fluid, and also protects the engine compartment against moisture.
High acoustic absorption levels in combination with reduced wall thicknesses
Impregnation against water, fuel, oil and brake fluid, etc.
Cost advantages due to one-shot production in a single tool
