Cavity foaming systems (acoustic and structure)

Cavity foaming systems (acoustic and structure)

Bodo Möller Chemie South Africa offers sprayable systems mainly based on polyurethane that are injected into rail 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 rail vehicle cavities
  • Improvement of stiffness and deformation behavior during impact
  • Application
  • Is injected into rail vehicle 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
