Detailed Product Description: | Polyester fiber sound-absorbing cotton is 100% of French imports of PSF from after overlay hot press bonding, it can make a sound through a special high density of the fiber organization in the cavity formed reflux, acoustic noise function; direct contact with human skin, does not produce any harmful effects, is a non-toxic, harmless, non-polluting new sound-absorbing material. The highest level of flame retardant can be achieved M1 grade (French NF F 16-101) is a flame retardant product; smoke density, gas to the F1 class (French NF F 16-101), these properties have reached France ALSTOM EMU project the highest requirements. Its acoustic performance has also been recognized by the Chinese Academy of Sciences and the American SGS. Advantages: 1,100% environmentally friendly products, 100% recyclable; 2, deformation of the rebound rate, long life; 3, sturdy, easy to use, easily processed into various shapes according to different needs; 4, will not rot and can withstand the corrosion of a variety of microorganisms, fungi, acids, salts and hydrocarbons; 5, tasteless, free of formaldehyde and other harmful substances; 6, waterproof, moisture, good air permeability; 7, in the production process does not add any additives, adhesives; 8, anti-aging, wear, washable and never deformed, soft, smooth. Performance: 1, compression of 2% (GB/T10295-1988); 2,45 degrees angle combustion: flame retardant grade (TB/T2402-1993); 3, noise reduction coefficient of the NRC ≥ 0.76 (GB 47-83); 4, hydrophobic: 98% (GB/T10299-1988); 5, water vapor permeability index of 2.46 * 10-6g / ㎡. S.Pa, (GB/T17146-1997). Purposes: A home office noise: walls, ceilings, roofs, partitions, conference room and other noise sound-absorbing insulation; Entertainment noise: KTV, dance halls, recording studios, audio-visual room, audiovisual room, piano room; theaters, studios, radio and television stations; stadiums, exhibition halls and other noise insulation; 3, soundproof acoustic insulation of the equipment room noise: cabin, engine room and other equipment, engine room, pump room noise, cold storage temperature; 4, with the use of the room sound insulation, acoustic doors, acoustic enclosures, separated from the speakers and other noise reduction facilities.
