Wood fiber sound insulation is an environment-friendly and recyclable material, which is made of wood fiber, cement and high-temperature and high-pressure water. It is made of about 65% poplar wood fiber and about 35% cement. The fibers are coated in cement and bonded together under pressure to form a stable, durable, compact and durable structure. It does not contain any industrial adhesive, and the formaldehyde emission complies with the national environmental standard E1. Fiber is a mineral substance. It is processed under high temperature and high pressure by continuous operation process, which can prevent the biodegradation process while maintaining the mechanical properties of wood, make the fiber completely inert, and improve its fire resistance. The fire resistance can reach the national B1 level.
