BETAFOAM™ Acoustical Foam Systems

BETAFOAM™ cavity fill foam offers superior NVH (noise, vibration and harshness) performance in Internal Combustion Engine (ICE) vehicles as well as Electric Vehicles (EV). BETAFOAM™ acoustic foams provide highly effective protection against airborne noise, improving overall vehicle acoustic performance when compared to baffle technology.


  • Cavity fill applications for NVH purposes.

  • Several BETAFOAM™ products also provide local reinforcement to body structures for crash and energy management.


  • Low cost solution providing OEM savings compared to baffles
  • Superior NVH performance in ICE and EV vehicles
  • Lightweight, mass-efficient solutions that reduce overall vehicle weight
  • Long-term performance vs baffles
    • Three-dimensional cavity seal
    • Does not dislodge over time
    • Avoids pinholing 
  • Recent innovations have reduced capital investment to implement technology

BETAFOAM low-density, lightweight formulations form high-performance acoustical seals to prevent noise from resonating in vehicle cavities. The two-component polyurethane foam consists of a low-MDI prepolymer that reacts with a polyol blend that serves as an acoustic cavity-sealing and blocking foam. These two-component polyurethane foams adhere to primed metal surfaces and combine insulating and sealing performance.
