POLYDAMP® Acoustical Foam (PAF)

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, and chemicals while being hydrolytically stable.

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

Applications typically include equipment engine compartments, power generation, and construction equipment.

POLYDAMP® Acoustical Foam - Ester Type (PAFS)

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 have superior physical properties and offer excellent resistance to heat, moisture, and chemicals.

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

Applications typically include medical equipment, business equipment, and equipment cab compartments.

POLYDAMP® Melamine Foam (PMF)

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

  • Density: 0.56 lbs/ft³
  • Temperature Range: continuous -300°F to +356°F; intermittent to +492°F
  • Thermal Conductivity: 0.25 BTU-in/ft²-hr-°F at 68°F
  • UL94 V-0 listed
  • Meets aircraft, HVAC, and transportation vehicle's flame, smoke, and toxicity standards
  • Resilient to vibration and compression set
  • Available with a wide variety of film facings and pressure sensitive adhesives.

Applications typically range from HVAC and ECS ducts to wall/fuselage insulation in aircraft, as well as power generation and mass transit.

POLYDAMP® Hydrophobic Melamine Foam (PHM)

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: 0.56 lbs/ft³
  • Temperature Range: continuous -300°F to +356°F; intermittent to +492°F
  • Thermal Conductivity: 0.25 BTU-in/ft²-hr-°F at 68°F
  • UL94 V-0 listed
  • Meets aircraft (FAA, BSS, etc.), HVAC, and transportation vehicle's flame, smoke, and toxicity standards
  • Resilient to vibration and compression set (unlike solimide/polyimide foam and fiberglass)
  • Facings available:POLYTECH® Metalized PVF and PEEK films (Aircraft approved), Reinforced Aluminum Foil, and others
  • Fire-retardant and standard pressure sensitive adhesives also available for easy installation

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

POLYDAMP® Melamine Foam Ultra-Flex (PMF-UF)

POLYDAMP® Ultra-Flex Melamine Foam (PMF-UF) is an extremely lightweight material that exhibits exceptional resistance to heat, low flame propagation, and smoke. Differentiating it from standard POLYDAMP® Melamine Foam, its flexibility and resilient nature makes it suitable for cushioning and other applications where more durable attributes are required.

  • Density: 0.44 lbs/ft³
  • Temperature Range: continuous -300°F to +356°F; intermittent to 492°F
  • Tensile Strength: 13.0 lb/in2 min
  • Compression Set: 10% max
  • Thermal Conductivity: 0.25 BTU-in/ft²-hr-°F at 68°F

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

POLYDAMP® Hydrophobic Melamine Ultra-Flex Foam (PHM-UF)

POLYDAMP® Ultra-Flex Hydrophobic Melamine Foam (PHM-UF) is an extremely lightweight and water resistant material which exhibits exceptional resistance to heat, low flame propagation, and smoke. Our ultra-flex hydrophobic melamine foam has all the same properties of the ultra-flex melamine foam (listed above) with the added benefit of being water resistant.

  • Density: 0.44 lbs/ft³
  • Temperature Range: continuous -300°F to +356°F; intermittent to +492°F
  • Tensile Strength: 20.0 lb/in2 min
  • Compression Set: 10% max
  • Thermal Conductivity: 0.25 BTU-in/ft²-hr-°F at 68°F

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

POLYDAMP® Melamine Foam Ultra-Lite (PMF-UL)

POLYDAMP® Melamine Foam ULTRA-LITE (PMFUL) is a 40% lower weight version of regular PMF, a material which exhibits exceptional resistance to heat, low flame propagation, and smoke.  It does not drip in the presence of a flame and stops burning after removal of any external ignition source and fuel.

  • Density:  0.375 lbs/ft³,
  • Temperature Range: continuous -300°F to +392°F; intermittent to +492°F
  • Tensile Strength:  13 lb/in2 min
  • Thermal Conductivity: 0.25 BTU-in/hr ft²-hr-°F at 68°F

PMF-UL is typically used in aerospace applications where high heat resistance and low flame spread and smoke are requirements.

POLYDAMP® Hydrophobic Melamine Foam Ultra-Lite (PHM-UL)

POLYDAMP® Ultra-Lite Hydrophobic Melamine Foam (PHM-UL) is a lightweight version of standard PHM, offering a roughly 40% reduction in density while continuing to exhibit the same exceptional resistance to heat and water, flame propagation, smoke generation, and toxicity.

  • Normal Density 0.375 lbs/ft³
  • Temperature Range: continuous -300°F to +356°F; intermittent to +492°F
  • Thermal Conductivity: 0.25 btu-in/ft²-hr-°F at 68°F
