Damping

WACKER silicone fluids and liquid and solid silicone rubbers combine ideal damping properties with high durability and reliability. This has made them an integral feature of modern automotive engineering and engine construction. Their superior functionality is particularly evident in applications that span a wide temperature range.

Benefits:

  • Constant damping over a very wide temperature range
  • Versatility due to adjustable damping properties
  • Fast curing
  • High tear strength
  • Low compression set
  • Outstanding heat resistance
  • High dynamic loading capacity

Applications:

Vibration dampers for

  • Airbags
  • Electronic components
  • Exhaust pipes
  • Engines
  • Vehicle bodies
