Polydamp Hydrophobic Melamine (PHM) foam from Polymer Technologies repels water, while keeping low flame, smoke and toxicity levels. The foam provides lightweight acoustical and thermal insulation for marine, aircraft, transportation and medical applications where water resistance, water retention resistance, low flame propagation and minimal smoke generation are required.
PHM has a density of .55 pounds per cubic foot and meets stringent FAR 23 and FAR 25 flame, smoke and toxicity requirements, including FAR 25.856 radiant panel testing, and all other vehicle standards. PHM is listed under UL 94 Flammability requirements with a V-O rating. Its operating temperature ranges from -300 degrees to 300 degrees Fahrenheit
Film facings, acoustical barriers and pressure sensitive adhesive backings are available.
