Foams for sound insulation and reinforcement - Designed for acoustic or thermal insulation properties in automotive market

Cavity foaming systems (acoustic and structure)
These sprayable systems mainly based on polyurethane are injected into cars and vehicle cavities to achieve a reliable shielding against air noise (acoustic systems). A very good increase of the rigidity by reinforcing structure foams results in weight saving and improvement of crash performance, since it can be designed and constructed with smaller wall thicknesses and without any additional reinforcing parts.

Benefits at a glance:

• Acoustic seal for preventing noise caused by resonance in car and other vehicle cavities
• Improvement of stiffness and deformation behavior during impact
• Application
• Is injected into car cavities, including pillars, sills and the roof frame, to protect reliably against wind noise and / or to act as an impact protection for the frame structure
