stable chemical composition:

　　NewTime Foundation Mineral wool sound-absorbing board granular fibrous wool with stable source of raw materials and partly artificial block technology make the physical and chemical properties of its finished wool very stable, ensuring that the mineral wool sound-absorbing board of the fiber-forming products has stable and excellent chemical performance.

　　NewTime Foundation Mineral wool acoustic board is a human health and environment-friendly industrial product which contains absolutely no any heavy metals and radioactive substances which are harmful to human health and the environment.

　　NewTime Foundation mineral wool sound-absorbing panels with granular fiber with excellent synthetic block technology, chemical composition of stable and controllable, which has a higher fiber strength (WT value ≥ 55), as a raw material to produce mineral wool Sound-absorbing panels with high strength, with excellent sag resistance,

　　NewTime Foundation Centrifugal fiber-optic equipment up to 8000 revolutions, the production of granular fiber diameter less than 5 microns, slag ball rate is low, as a raw material to produce sound-absorbing panels with lower density, light weight, with better sound absorption Performance, the same weight granular mineral wool, can produce more mineral wool acoustic panels, effectively reduce the cost of mineral wool acoustic panels customers;

　　The color stability, to ensure that as a raw material of mineral wool sound-absorbing panels also have a more stable and pure finished color.
