摘要:
To satisfy the fire protection requirements for a sound-absorbing material, especially in the form of open-cell foam, without impairing the acoustic properties, at least a part of the surface of the sound-absorbing material, which is covered with an acoustically transparent film, is coated with a flame-retarding powder or sprayed with a flame-retarding solution.
