THERMOFORMABLE ACOUSTIC PANEL

摘要

PROBLEM TO BE SOLVED: To provide a flexible acoustic panel which can be molded and embossed, is highly acoustically absorptive and has a smooth and paintable surface and to provide the panel which is relatively durable and has a high NRC value when the panel is thin and the panel which is not sensitive with moisture and does not require coating or requires a back coating system in order to prevent the panel from sagging under a moist environment. SOLUTION: The acoustic panel including the material selected from the group consisting of multicomponent polymer fibers which are multicomponent fibers respectively having sheath layers substantially enclosing inner cores and including first polymers having the melting point lower than the melting point of second polymers forming the inner cores; slag cotton, fiber glass, cellulosic materials and their combinations.
