The main material is the mineral cotton of high quality. It does not contain any asbestos and con not make wool dust of needle shape which may enter into human body through breath, so it will do no harm to human body. The using of , compound fiber and surface coating of net structure will greatly improve the ability of impact and deformation resistant of the mineral wool board. The internal structure of mineral wool board, forming into netted- structure with enough space , is very firm and greatly improves the sound absorption ability of it .the effect of sound absorption is one or two times than ordinerary mineral wool boards. The adding of desccant and assistant desiccant improves the ability of impact resistant, adhesive matrial firming, the board rigidity holding as well as the indoor humidity accommodating and inhabited environment improving.
