Glass fiber sound insulation cotton - Excellent sound insulation effect, safe and convenient

.Environmental conservation

The release amount of harmful substances of polyester fiber acoustic panel has been tested by relevant state departments, and its formaldehyde release amount is 0.05mg/L(standard requirements ≤ 1.5mg /L), which meets the requirements of the national standard E1 level. The product has no special odor and will not cause skin allergies. And the polyester fiber that used to make sound absorbing panels can be recycled. Therefore, this product is truly environmentally friendly.

• Size: 1000mm×500mm, 1220mm×610mm two standard specifications, suitable for most conventional building structures. At the same time, specific sizes can be customized according to special spatial layouts, ensuring seamless integration into various environments.

• Thickness: Available in 20mm, 30mm, 40mm three thickness options. The thin 20mm panel is suitable for scenarios where installation space is limited and high-frequency noise needs to be absorbed. The 30mm panel has excellent comprehensive performance and is widely used in general acoustic environment optimization; The 40mm panel is excellent at low frequency sound absorption and is suitable for places with high requirements for low frequency control.

• Material: The surface is environmentally friendly wood veneer, the texture is natural and beautiful, the touch is warm, and it can be integrated with various interior decoration styles; The internal sound absorption core adopts a new type of polyester fiber sound absorption cotton, which has the characteristics of uniform density and good elasticity, and meets the strict environmental protection standards while ensuring efficient sound absorption, non-toxic and tasteless, harmless to the human body and the environment.

• Sound absorption performance: According to the international standard ASTM C423 test, in the full frequency range of 100Hz-6300Hz, the average sound absorption coefficient (NRC) can reach 0.8 or more. Among them, the absorption effect of medium frequency (500Hz-2000Hz) and high frequency (2000Hz-6300Hz) sound is particularly significant, and the absorption coefficient is as high as 0.95, effectively eliminating the sound turbidity and restoring the true sound. Even in the low frequency band (100Hz-500Hz), it can maintain good sound absorption performance, and the sound absorption coefficient reaches 0.65, effectively reducing the low-frequency resonance and standing wave phenomenon.

• Fire performance: meet the national B1 flame retardant standard, it is not easy to burn in case of open fire, can effectively delay the spread of fire, and provide reliable guarantee for the safety of the site.
