100% polyester fiber is hot-pressed with high technology and made in the shape of cocoon cotton to achieve density diversity and ensure ventilation. It has become an excellent product in sound-absorbing and heat-insulating materials. According to different needs, the adjustment reverberation time is shortened, the sound impurities are removed, the sound effect is improved, and the language intelligibility is improved. QDBOSS polyester fiber acoustic panel has patented flame retardant technology, which perfectly fuses flame retardant and fiber to achieve permanent flame retardant effect. Among them, the products have the characteristics of decoration, heat preservation, flame retardant, environmental protection, light body, easy processing, stability, impact resistance, easy maintenance, etc., and have become the preferred decorative sound-absorbing materials for interior decoration.
The fire performance of sound-absorbing materials in public gathering places such as theaters, dance halls, auditoriums, multi-purpose halls, gymnasiums, etc. is very important. The polyester fiber sound-absorbing board has been tested by the National Fire Protection Testing Center on the fire parameters. The results show that it has good fire performance, meets the requirements of the national standard GB8624B1 level, reaches the B1 level, and has passed the American flame retardant test and European quality certification.
