The Polyester acoustic Panels are sound absorbing panels developed with environmental friendliness in mind. The Polyester Acoustic panels are made from 100% polyester and are 100% recyclable. Panels offer many environmental advantages over the traditional fiberglass sound absorption panel.

FEATURES: Formaldehyde free No binding agents No odor and dust free No risk of skin irritation or respiratory problems 100% recyclable Fire Rated:can meet China Standard Class B1 and BS476 Part 7 Class 1 Eco Level :can meet China and EU Standard Class E0 Sizes: 2420mm*1220mm Thickness: 9mm/12mm/24mm Fire Rating: Class A per ASTM E84 Meets: IAQ emission Requirements of CA Section 01350 Core: 100% Polyester Fiber Edge Detail: Square Mounting options: Impaling Pins and construction adhesive or mechanical fasteners as appropriate APPLICATION: Commercial and office buildings, Call center, Music rooms, recording studios, home theaters, Sport stadiums, multipurpose halls, school halls, Indoor swimming pools, Industrial buildings, such as factories, pump rooms, control rooms , plant rooms, fan rooms, compressor rooms, generator rooms Difference between A grade panel and B grade panel    A Grade panel  B grade panel materials High quality Polyester fiber material   Ordinary Polyester fiber materia  Color evenness Very good Good Source of raw materials  virgin fiber 60%  recycled fiber, 40%  irgin fiber Colors 34 35 NRC same same

High quality Polyester fiber material   Sound absorption principle of Polyester Panels:  fiber porous sound-absorbing material, The sound absorption principle is a large number of tiny pores in the material, Can be deep inside the material, and material friction occurs to the sound energy into heat. Fiber porous sound absorption material sound absorption characteristics: with the frequency increases the sound absorption coefficient gradually increased .  Polyester Panels internal fiber fluffy staggered, there are a large number of tiny pores, is a typical porous sound-absorbing material, with good sound absorption characteristics .   Good impact resistance: With soft and natural texture, acoustic polyester fiber panel is high impact resistance and abrasion resistance . and will not be destroyed easily. it often be usded in decoration for sport stadiums, dance room.
