Sound-absorbing |
100% polyester fiber become hard sound-absorbing panels under compression , and has sound-absorbing function.It can absorb indoor sound and reduce sound reflection, thus reducing the noise. |
Securely and Safety |
Any adhesive materials is not used during the production of sound-absorbing panels , this is a product which does not contain formaldehyde, Adhesive products is also in accordance with the standards of F☆☆☆☆☆,your child can get a safe living environment, there is no any stimulating smell with product. |
Dyeing fastness |
The result from professional testing department is light fastness test ・ ・ ・ 4 class above / friction test ・ ・ ・ 4-5 grade (wet ・ dry), has a very high dyeing fastness.Please feel free to use, sunlight, or the friction in the process of using won't make color off. |
Ventilation |
The average of ventilation is 50 ㎤ / ㎠ ・ S amount by air (* 1 second).Compare with the general wall( average 30 ㎤ ventilate / ㎠ ・ S), ventilation is quite high. |
Flame retardant |
The flame retardancy of high fiber density of sound-absorbing panels is very high, up to t international standards of ASTM E84-08, in addition, also meet the fire of the flame retardant test method standard of Japan's communications ministry . |
Intensity ・wear resistance |
The fiber strength of Polyester fiber is strong, and with good material durability in the fiber. The size change rate is about 1.2% . in wear resistance test , the change of appearance almost can not be find out.So the surface strength is very strong. |
Processability |
It can be cut with simple tools such as knife etc. For indoor walls, pillars, such as the floor where the size adjustment, it can be make out simply. In addition, there are all kinds of processing methods such as 3 D processing, carving, and joint etc. |
