Muffler Hangers, Dampers


Add design flexibility and NVH control to exhaust systems with proven silicone elastomers

Choose Silastic® brand silicone elastomers from Dow Corning for tough, longer-lasting muffler hangers and vibration dampers. We can help you meet specifications for restricted-space, high-temperature system layouts.

High-performance silicone rubber muffler hangers and dampers


Our range of high-performance Silastic elastomers can help you increase your exhaust system layout options and improve sound deadening. Silastic elastomers:

  • Maintain mechanical strength and performance properties in searing heat and freezing cold, from -40 to 200°C (-40 to 392°F).
  • Provide long-term resistance to degradation from road salts, chemicals and solvents.
  • Offer a choice of tough, high consistency silicone rubber (HCR) elastomers, easy-to-process liquid silicone rubber (LSR) elastomers, and fluorosilicone rubber (FSR) elastomers for added resistance to fuels and oils.

Gain 3D design flexibility
Muffler hangers and dampers made with high-performance Silastic elastomers can expand your design choices and processing options:

  • Liquid silicone rubber (LSR) elastomers allow high-speed, economical injection molding for high volumes.
  • Fluoro liquid silicone rubber (F-LSR) elastomers provide excellent fuel and oil resistance in a liquid elastomer for faster processing speeds and lower costs.
  • Custom compounds can be used to meet special application or system layout requirements.
  • Product properties can be tailored for maximum 3D design flexibility.
