Specification :

1, polyester fiber is sound-absorbing board product is mainly used in indoor ( metope, ceiling)
2, polyester fiber is sound-absorbing board is a porous material, magnified three hundred times as much to talk, we see the polyester fiber is sound-absorbing board is porous structure, it is because these cavity, polyester fiber is sound-absorbing board can sound-absorbing ( voice after polyester fiber sound-absorbing panels in cavity formed by sound energy into backflow, heat) .
3, decoration plasticity, use common wall paper knife, it can cut.
4, polyester fiber materials, what is polyester fiber ( PET) , polyester fiber material is oil chemical materials, commonly known as the polyester, is in the state of wire drawing, color after pressing into boards.
5, has sound-absorbing, fire prevention, environmental protection, noise reduction, moistureproof, characteristics, sound-absorbing, fire prevention, environmental protection for instructions
( 1) polyester fiber is sound-absorbing board sound-absorbing mainly reflects in sound-absorbing noise reduction coefficient, according to GB/ T20247-2006, average noise reduction coefficient ( NRC) of 0.85 above, average absorption coefficient ( 100 HZ ac-4 KHZ) was 0.72. In the high frequency band, for better effect.
( 2) polyester fiber is sound-absorbing board for national fire protection GB8624 B1 level ( 1997) national fire protection has four grade level A: doesn' t burn. ( like stone, steel, etc) B1 level: flame retardant. ( mainly refers to fire left the fire spread speed slow) B2 class: flammable ( as long as it' s wood, etc.) B3 level: flammable ( alcohol, fuel)
( 3) environmental protection level is divided into: E0 level, E1, E2 class
Polyester fiber is sound-absorbing board far accord with a country ( the gb18580-2001) E1, formaldehyde to release a quantity to < 0.1 ( mg/ l) , index more than 1.5 mg/ requirements ( l) , which can be directly used for indoor
Fields: home cinema, hotel, studio, the music room, KTV, bars, theaters, meeting rooms, multi-function hall, the indoor stadium, etc
