How the Right Adhesive Helps You Meet NVH Standards

Today’s consumers increasingly prefer a quiet, comfortable driving experience. Therefore, it’s become imperative to OEMs that all vehicle components meet noise, vibration and harshness (NVH) standards to address consumer needs and increase vehicle sales. Gain further insight into the importance of achieving ideal levels and how the right adhesives can help.

Importance of Achieving NVH Standards

The main purpose of NVH testing is to ensure that all vehicle components contribute toward a luxurious driving experience for drivers and passengers. Arguably one of the most crucial determining factors in the success of a vehicle, ideal NVH levels don’t just contribute toward a quieter ride. They also increase a vehicle’s perceived level of quality and market value.

Once NVH targets are set at the beginning of a project, vehicle components are exposed to different vibration frequencies. This helps determine ideal mode shapes and isolate any buzzes, noises or rattles. Then, continued testing and benchmarking ensures that the NVH targets for the vehicle are met.

While this can be a time-consuming process, it’s also an imperative one. Failure to meet NVH levels could result in poor vehicle sales and decreased quality perception of the automotive brand.

How the Right Adhesive Aids in Reaching NVH Levels

Fortunately, the right adhesive can help in meeting NVH levels and aid in OEM reassurance. For example, SMP (silyl modified polymer) technology can be used to bond polyurethane foam to tire cavities.

Tire cavities can be a major contributor to noise, as air bounces around within them. However, SMP offers inherent sound and vibration dampening properties, which reduces the noise. Additionally, SMP offers:

  • Limited surface treatment needs: For many applications, SMP doesn’t require a primer. This increases OEMs’ manufacturing efficiencies
  • No solvents or isocyanates: This improves worker safety during vehicle assembly.
  • UV and oil resistance: This allows for improved end-use vehicle performance.
