non-combustible acoustic finish : 
Material characteristics : MA series adopts soundbox custom inorganic microporous fiber composite acoustic cotton, custom acoustic
cotton is different from traditional insulation cotton, semi-rigid fiber, long fine fiber 35-40mm/5.5-6.0μm
(insulation cotton is usually 15-20mm/7.5-8.5μm short thick flexible and rigid fiber)
Common Specifications : W600 * L1200/1800/2400 * D32/52mm
Environmental characteristics : The environmental protection characteristics of Baililong fiber advantages, particle release ≤0.06mg/m ³
(national E1 standard value ≤0.15mg/m ³), zero 甲醛maldehyde (TVOC organic compound gas is not detected)
Acoustic characteristics : Inorganic semi-rigid and long-fine fiber custom acoustic cotton, the physical creation of a smooth fine long hole
superimposed air layer, forming a strong broadband absorption effect, custom acoustic cotton products up to ≥0.96
(equivalent to 1.5 times the insulation cotton).
Design characteristics : MA30/50 is a horizontal mounting model, unique space sandblasting aluminum metal texture, acoustic cloth surface
process, the back of the non-equivalent blocking sound absorption surface, matrix is not only efficient absorption of
space sound.
Sound absorption coefficient :
