Cellasto® reduces NVH in automotive chassis

Improve driving comfort by reducing noise, vibration and harshness (NVH) in automotive chassis components with Cellasto®. Load-bearing structures experience NVH from road surfaces as well as from moving parts throughout the automobile. But the special microcellular and compact polyurethane elastomers of Cellasto® efficiently manage the disturbance, no matter what the source.

  • Influence the load deflection curve for jounce bumpers with or without a support ring, spacer and cup
  • Reduce peak loads with high energy absorption
  • Create a smaller package for the shock absorber strut allowing a larger dust cover capacity
  • Lower the total component cost with lighter weight and smaller packages
  • Optimize component design to achieve a stiffness-optimized force-displacement characteristics that leads to optimum ride comfort

 

Coil spring isolator

Protect the suspension and the interfaces in even the most challenging driving environments with coil spring isolators made from Cellasto®. As a durable, quiet base for your springs, Cellasto® coil spring isolators will last the lifetime of the vehicle, preventing metal-on-metal wear, and will:

  • Efficiently damp coil spring resonances for high and low amplitudes
  • Reduce chassis and road-borne noise
  • Provide lifelong performance with excellent durability, dirt- and abrasion-resistance
  • Reduce costs when you combine coil spring isolators with an end stop or jounce bumper in one component

Damping system

Cellasto® can provide one fully assembled damping system that guarantees the perfect interaction of top mount, jounce bumper, coil spring isolator and dust cover. This will:

  • Effectively reduce dynamic wheel loads, increasing road safety
  • Manage load peaks to minimize rumbling noises in the shock absorber
  • Improve decoupling between the road surface and body thorugh excellent vibration and noise isolation at high and low amplitudes
  • Damp inherent wheel frequency, while reducing irritating vibrations
  • Gain more design freedom, reduce weight and lower costs with high volume compressibility 
  • Achieve excellent vibration and noise insulation readiness for high and low amplitudes
  • Choose lighter aluminum inlay and eMobility with reinforced housing for cost savings designs to cover higher battery pack loads
  • Access BASF expertise to develop housings in plastic materials for even more weight savings
  • Achieve outstanding durability performance overall

Steering isolation

As a steering element, Cellasto® manages radial loads with its high volume compressibility, allowing you to deliver improved safety as well as superior handling for an exciting driving experience.

  • Simultaneously satisfy NVH as well as vehicle handling challenges
  • Reduce steering vibration on rough surfaces with efficient decoupling
  • Deliver dynamic steering at any speed with ideal acoustical isolation and stiffness
  • Create new coupling and bushing designs for unique automotive challenges
