Is polyester fiber sound proof board environmentally friendly?
Polyester fiber sound-absorbing board, known as polyester fiber decorative sound-absorbing board, is a polyester fiber as raw material, made by hot pressing, with sound-absorbing function of decorative materials.
The material properties of 100% polyester fiber with high technology and hot pressing with cotton cocoon shape, density diversity to ensure ventilation, become a good product and sound-absorbing insulation materials. In the 125~4000HZ range of the highest noise absorption coefficient reached more than 0.9, according to the different need to shorten the adjustment reverberation time, sound clear impurities, improve sound effect, improve language the definition of. Products with decorative, heat preservation, flame retardant, environmental protection, light body, easy processing, stability, shock resistance, easy maintenance and so on. Become interior decoration of the preferred decorative sound-absorbing materials.
The safety performance of polyester fiber board in two aspects, on the one hand materials with excellent mechanical properties, light weight, impact damage will not be as brittle materials such as perforated plasterboard and fiber cement pressure plate, are in danger of falling debris or debris. On the other hand, the release of harmful substances, detected by the state departments, the formaldehyde emission standard is less than or equal to 1.5 mg of /1, the test result is 0.05 mg /1. To meet the national standard GB18580-2001E1 level requirements, in line with the requirements used directly for interior decoration.
