Cellasto® reduces NVH in the automotive body

In automobiles, the body takes a beating. From potholes in the road to vibrations between internal touchpoints, there are many opportunities for noise, vibration and harshness (NVH) to transfer from the vehicle to your customer. Create a noticeably smoother, quieter driving experience by using Cellasto® in automotive body components. This versatile microcellular polyurethane elastomer efficiently reduces NVH, regardless of the origin.

Mounts for unibody passenger vehicles

Automotive body mounts made with Cellasto® reduce NVH from road surfaces

BatteryMount_cellasto.png
  • Use in dampers for doors to avoid the harsh sounds of metal-on-metal    

  • Lighter weight parts make the car more fuel-efficient and easier to handle

  • Isolate noise and acoustics by adding Cellasto® acoustic pads around batteries and speakers, reducing rattling or “booming” noises resulting from the transmission of vibrations from the battery box to the body
  • For additional NVH reduction, you can isolate an entire subframe using Cellasto® to reduce vibrations from motor and steering mechanisms, road noise and vibrations, thereby creating a smooth, sleek ride

 

Cabin or ladder mounts for body-on-frame trucks

Trucks and commercial vehicles weather the most challenging conditions, but durable doesn’t have to mean heavy. With Cellasto®, cabin mounts are lighter and put less strain on the components attached to them while protecting the driver from NVH.  

  • Reduce noise originating from the road and subsequent vibration into the cabin

  • Damp vibrations from chassis and powertrain as well as any resonance effects

  • Transfer high static loads of the body, creating a safer, more comfortable ride

  • Provide lifelong performance with excellent durability and abrasion resistance

  • Reduce the overall weight of the vehicle with Cellasto® cabin mounts while gaining high energy absorption and lighter components
  • Save space by reducing component height due to high compressibility and low lateral expansion behavior of the material
