Soundfiber AF UL
Soundfiber AF UL is an engineered blend of polyester sound absorption materials designed to withstand high temperatures up to 150⁰C continuous. The vertically lapped lofted layer is laminated with a polyester nonwoven engineered facing to maximize the sound absorption qualities of the composite.
Soundfiber AF UL is UL 94 HF-1 certified for applications requiring high flammability resistance. The polyester fibers are naturally hydrophobic resulting in a material that does not wick water and dries nearly twice as fast as other acoustic materials such as open cell foams.
Soundfiber AF UL is ideal for demanding applications where foam is simply not durable enough or will not meet the required operating temperatures.
