Specifications

Grade A1 incombustible materials.
Easy for construction; Cutting at will.
Antisepsis, ageing resistance, and anticorrosion,

Distinctive advantages:
Unique technology; Rebound degree after compressive packing is up to 99.2%.
Soft and long glass fibers can maximally lessen flying catkins in the construction.
Sound absorption and noise reduction; It can effectively prevent sound from spreading.
Grade A1 incombustible materials.
Easy for construction; Cutting at will.
Antisepsis, ageing resistance, and anticorrosion, ensuring a healthy environment.
Low moisture absorption; Stable physical properties.

Scope of application:
It is widely used for heat insulation and sound absorption in industrial workshops, warehouses, public facilities, exhibition centers, shopping malls, and a variety of indoor playgrounds, sports stadiums and etc.
