SOUNDALLOYâ„¢ MPM

SOUNDALLOYâ„¢ MPM is a fully damped aluminium composite comprising two layers of aluminium laminated together using a layer of a viscoelastic, thermoplastic, to form the laminate.

Using the “constrained layer� principle the function of the thermoplastic interlayer is to damp disturbing structure borne sound.

SOUNDALLOY MPM is free from resonance and coincidence phenomena which often detract from the performance of other acoustic insulation materials.

Applications

• Engine rooms for high speed craft / vessels
• Machinery and equipment enclosures
• Compressor and generator set enclosures
• Acoustic hoods / chutes
• Conveyor systems
• Crushers / granulators
• Coin counters
• Automotive sumps, panels etc.
• Air conditioners
• Acoustic walls
• Acoustic doors

Benefits

• Effective “in-structure damping�
• No need for external damping materials
• Reduces or eliminates need for use of external isolators
• Lightweight damped structures
• Maximum damping for minimum thickness
• Broad temperature range (0°C to 100°C)
• Use conventional machine shop tooling, shaping, cutting and joining systems
