New insulation materials

material properties Polyester fiber decorative acoustic board composed of absorber in addition to the high absorption coefficient and wide-frequency sound absorption and excellent acoustic properties, the victims have good physical and mechanical properties and interior decoration of the performance. acoustic performance Polyester fiber decorative acoustic board and other porous materials sound absorption characteristics similar to the absorption coefficient with the improvement and increase in the frequency, high-frequency sound absorption coefficient of a large, empty cavity back, as well as its use of space consisting of absorber Can enhance the absorption properties of the material.

Noise reduction coefficient more or less around 0.8-1.10 become high-performance broadband absorber. physical and mechanical properties Polyester fiber decoration with acoustic insulation properties, and a solid plate of uniform material, flexible Toughness, wear resistance, impact strength, tear-resistant and difficult to cut through, large pieces of plate (1220 ×
