Why Is Polyester Fiber Acoustic Panel the First Choice?
First of all, sound absorbing materials such as glass wool, rock wool and sponges should not be considered for indoor sound insulation materials. Glass wool and rock wool, because their raw materials are brittle fibres, will easily enter the skin, thus causing skin allergies, and their layering into the room will cause respiratory allergies. Sponges are flammable products and produce toxic gases when they burn. Although they are porous materials and have some sound absorption, they are still not recommended. Polyester fibre acoustic panels are a hot selling material for sound insulation and sound absorption and are widely used in a variety of locations. In general, the ability of sound-absorbing panels to absorb low frequencies increases as their density increases, however, when the density reaches an upper limit, the ability of sound insulation and sound absorption also reaches its limit. Polyester acoustic panels are a 100% polyester fibre sound insulat...
