FOAM & SEALANT Integrated technologies for quieter and safer mobility

In the context of profound transformation in extended mobility, tire manufacturers are integrating advanced acoustic foam and sealant technologies into tires to meet growing expectations in terms of comfort, safety, energy efficiency, and sustainable mobility.

Optimized acoustic comfort

With the reduction of powertrain noise, particularly in electric vehicles, cavity noise has become a key factor in in-cabin comfort.
Cavity noise reduction solutions, based on polyurethane foam inserts bonded to the tire, make it possible to reduce interior noise by 3 to 9 dB(A), without any modification to the tread design or the suspension. Exterior noise is reduced by 1 dB(A).

In case of a puncture, the sealant helps maintain the tire pressure.

Safety and extended mobility

Integrated sealant technologies provide active protection against punctures. In the event of a perforation, the tire automatically seals itself, allowing pressure to be maintained and driving to continue safely until a service point is reached.

Lighter than traditional run-flat solutions, foam and sealant technologies help to:

  • Reduce vehicle weight,
  • Decrease rolling resistance,
  • Improve range and energy efficiency.

Eliminating components such as the spare wheel also contributes to overall vehicle optimization.

Essential Solutions

Foam & Sealant technologies are no longer optional. They have become key elements of modern tires, supporting the commitment to quieter, safer, and more sustainable mobility.
