Easy to shape and cut to size, changes will not affect performance.
Flame retardant, self-extinguishing after 3 seconds on the open flame, reducing safety risks. But it should be noted that burning on an open flame for a long time will destroy the flame retardancy and make the sound insulation cotton burn.
