  Cellasto MH24-35材料說(shuō)明

  Cellasto is the trade name for BASF Polyurethanes' high performance, microcellular polyurethane elastomer. Cellasto components have been used successfully for over 35 years as the NVH (Noise, Vibration, Harshness) solution for automotive chassis and suspension applications such as jounce bumpers, shock absorber top mounts and coil spring isolators. Cellasto is also used in many other applications outside of automotive such as: elevator safety buffers; paper conveying components; friction dampers; sub-frame, motor & body mounts; and more.
  
  The outstanding features are:
  

  • Low compression set

  • High volume compressibility with minimum lateral expansion

  • Excellent mechanical properties & durability

  • Highly versatile - noise isolation at small amplitude & high frequency; vibration isolation at large amplitude & low frequency

  • Abrasion resistant

  • Resistant to ozone, oils, greases and other aliphatic hydrocarbons
