什么 BETAFOAM™ Acoustical Foam Systems?
BETAFOAM™ acoustic open and closed cell cavity filling foams offer superior noise, vibration, and harshness (NVH) reduction in internal combustion engine (ICE) and electrical vehicles (EV). These two-component polyurethane foams serve as a cavity-sealing and blocking foam. BETAFOAM™ low-density, lightweight formulations provide effective protection against internal and external noises within the vehicle cavities, improving overall acoustic performance compared to baffle technology.
用途
- Cavity fill for noise, vibration, and harshness purposes to reduce:
- Road noise
- Wind noise
- Engine noise
- Motor frequencies
优势
- Superior low frequency insertion loss performance compared to baffles
- Recent innovations have reduced capital investment needed to implement technology
- One-time capital investment for plant vs. tooling for each part
- Avoid price creep of parts through the development process
- Part number reduction (only need two for the program)
- No capital cost to modify location, size, or additional treatment areas in the vehicle
- No capital cost for next vehicle program
