Noise Absorber/Sound Absorption Foam

Polydamp® Acoustical Foam Ether Type

Polydamp® Acoustical Foam (PAF) is an acoustical grade, open cell, flexible ether based urethane foam designed to give maximum sound absorption per given thickness. Ether foams offer excellent resistance to heat, moisture, chemicals and are hydrolytically stable.

• Density:  1.8lb/ft³
• Temperature Range:  -45 deg F to 212 deg F, Intermittent 250 deg F
• Flammability: UL94 - HF-1 Listed
• Available with a wide variety of film facings and pressure sensitive adhesives 

Applications include medical equipment, power generation and construction equipment.

Polydamp® Acoustical Foam Ester Type

Polydamp® Acoustical Foam (PAFS) is an open cell, flexible polyester based acoustical grade, polyurethane foam designed to give maximum sound absorption per given thickness. Ester foams offer excellent resistance to heat, moisture, chemicals and superior physical properties. 

• Density:  2.0lb/ft³
• Temperature Range:  -45 deg F to 212 deg F, Intermittent 250 deg F
• Flammability:  UL94 - HF-1 Listed
• Available with a wide variety of film facings and pressure sensitive adhesives

Applications include medical equipment, business equipment & equipment cab compartments.

Polydamp® Melamine Foam (PMF)

Polydamp® Melamine Foam (PMF) is an extremely lightweight insulation material which exhibits exceptional resistance to heat, low flame propagation and smoke. It possesses excellent thermal and acoustical insulation properties.

• Density of 0.60 lbs/ft³
• Temperature range continuous -300 to 300 deg F; intermittent to 375 deg F
• K factor of 0.25 at 68 deg F
• UL94 V-0 listed
• Meets all aircraft, HVAC and transportation (rail) flame, smoke and toxicity standards
• Resilient to vibration and compression set
• Facings available: Reinforced Aluminum Foil, Tedlar, Fire-Retardant Urethanes, and others
• Pressure Sensitive Adhesives also available for easy installation

Applications range from HVAC and ECS ducts to wall/fuselage insulation in aircraft, mass transit, and many others.

Polydamp® Hydrophobic Melamine Foam

Polydamp® Hydrophobic Melamine foam (PHM) is an enhanced version of PMF, offering exceptional water-resistance properties, previously unattainable with standard melamine foam, while maintaining all other key attributes. This melamine acoustic foam floats indefinitely in water; water streams bead-up on the surface and roll-off.

• Density of 0.63 lbs/ft³
• Temperature range continuous -300 to 300 deg F; intermittent to 375 deg F
• K factor of 0.25 at 68 F
• UL94 V-0 listed
• Meets all aircraft (FAA, BSS, etc), HVAC and transportation (rail) flame, smoke and toxicity standards
• Resilient to vibration and compression set (unlike solimide/polyimide foam and fiberglass)
• Facings available: Metalized PVF and APK films (Aircraft approved), Reinforced Aluminum Foil, Tedlar, Fire-Retardant Urethanes, and others
• Fire-retardant and standard pressure sensitive adhesives also available for easy installation

Applications range from HVAC and ECS ducts to wall/fuselage insulation in aircraft, mass transit, and many others.
