1, Features of Polyester Fiber Sound Absorption Board:
1) The products have more than 40 colors, which can be assembled into various patterns,the shapes include plane, square, wide strip and thin strip,the products can be bent into curved surface shape, making the interior design more effective.
2) There are a large number of tiny connected pores in the product,the sound wave penetrates into the interior of the material along these pores, and the sound energy is converted into heat energy to achieve sound absorption effect.
3) It is non-toxic and tasteless, with a very low formaldehyde emission of 0.05mg/L.
4) Good toughness, impact resistance, tear resistance and wear resistance.
5) Thermal insulation.
6) Flame retardant, fire rating B1 grade.
7) Easy to process and maintain.
2, Application: conference room, KTV room, concert hall, gymnasium, business hall, TV, interior decoration, etc.
3, Specification:2440 *1220*(5-20)mm
