Engine Mounts

The right engine mounts can help to control NVH and reduce vehicle mass

Evaluate Silastic® brand silicone and fluorosilicone elastomers from Dow Corning for fabricating special-
design engine mounts that effectively isolate and dampen
noise and vibration. With superior heat resistance compared to organics, silicone rubber engine mounts can help reduce vehicle mass by eliminating the need for heat shields.

Tighter clearances and higher temperatures are challenges
Silastic silicone high-consistency rubber (HCR), liquid silicone rubber (LSR) and fluoro liquid silicone rubber (F-LSR) elastomers can give you options for design, processing speed and added fuel and oil resistance for advanced engine mounts that can:

• Fit tighter tolerances and endure higher underhood temperatures.
• Resist long-term heat aging without losing elasticity or mechanical strength.
• Reliably dampen noise and vibration without requiring heat shields.
• Resist degradation from engine fluids, solvents and environmental contaminants.

Custom compounds can meet design-specific requirements
Rely on Dow Corning's elastomer compounding expertise for help to:

• Meet your NVH-control objectives in the face of rising underhood temperatures.
• Reduce costs by increasing productivity and eliminating mass (heat shields).
• Achieve complex 3D engine mount designs and fulfill proprietary engine-mount design objectives.
