Is the polyester fiber sound absorbing board environmentally friendly?
Polyester fiber sound-absorbing panels called polyester fiber decorative sound-absorbing panels, is a polyester fiber as raw materials made by hot-pressing sound-absorbing function of decorative materials.
Material properties 100% polyester fiber by high-tech hot and made of cocoon cotton shape, to achieve density diversity to ensure ventilation, as sound and heat insulation materials in the excellent products in the 125 ~ 4000HZ noise range of the highest sound absorption coefficient of 0.9 Above, according to different needs to shorten the adjustment of reverberation time, clear the sound impurities, improve sound effects, improve language clarity. Products with decoration, insulation, fire-retardant, environmental protection, light body, easy processing, stability, impact resistance, easy maintenance and so on. As the preferred decoration of the interior decoration sound-absorbing material.
Polyester fiber sound-absorbing board safety performance in two aspects, on the one hand the excellent mechanical properties of materials, light weight, impact damage will not like some brittle materials such as perforated gypsum board and cement fiber pressure plate, etc. The block is in danger of falling. On the other hand is the release of harmful substances, the relevant state departments to detect, the formaldehyde emission standards require ≤ 1.5 ㎎ / 1, the test results for 0.05 ㎎ / 1. To meet the national standard GB18580-2001E1 level requirements, in line with the direct requirements for interior decoration.
