Ultra-clean sound-absorbing panels are a general-purpose sound-absorbing material designed for different acoustic applications. They have excellent sound absorption performance and act as a barrier to sound waves (transmission loss); they can damp vibration problems and eliminate fluid-solid coupling (vibration isolation). The effect will be better when combined with other materials such as perforated panels, aluminum panels, etc. to form a composite module.

hbc can provide various waterproof and vapor-proof facing materials required for glass wool felts for steel structures, and process and compound them on glass wool felts in the original factory to meet various environmental requirements. It can greatly reduce the loss of heat and cold, not only has a beautiful appearance, but also has excellent moisture-proof and heat-insulating properties.

It does not contain formaldehyde and other harmful substances, and achieves a comfortable indoor air environment without odor.

The open-cell structure is combined with a composite pore design to achieve effective absorption of airborne sound over a wide frequency band; the unique combination of physical properties maximizes absorption at critical noise frequencies.

The relatively high density and high flow resistance provide an effective barrier to sound waves and can replace multi-layer composite foam sound barriers to a certain extent.

It has extremely high construction convenience and excellent cost performance, better insulation and decorative effects and lower overall cost.
