The fiber is slender and the average diameter is ≤5μm, which is lower than the national standard ≤6μm; the slag ball content is low, about 5%, which is lower than the national standard ≤7%. The measured thermal conductivity is 0.035-0.043w/m·

Using natural basalt as the main raw material, the melting temperature is greater than 1000 ℃, and the organic content is extremely low. It is a non-combustible A-level fireproof and thermal insulation material. It has excellent high temperature resistance and low thermal...

Hydrophobicity ≥99%; short-term water absorption (partially immersed in water 24h) ≤0.4kg/㎡; long-term water absorption (completely immersed in water 28d) ≤1.0kg/㎡; if the product is wetted by high-pressure water, its performance will not be affected after drying. Will not swell...

Rock wool products are fully immersed in an environment with a temperature of 50°C and a relative humidity of 95% for 25mm for 2 hours, and the volumetric moisture absorption rate is less than 5%; in accordance with the national standard GB/T25975-2018 test, the mass moisture...

Rock wool products are made of a large number of slender fibers to form a porous interconnected tiny air gap structure. It absorbs sound by converting sound energy into heat and greatly reduces sound wave reflection. It is a cost-effective sound absorption and noise reduction and...

The fiber structure of the rock wool board has good air permeability, and the water vapor can pass through freely. It can well cooperate with the respiration of the brick-concrete wall or the concrete wall, so that the room can maintain a comfortable dry and humid environment.

The acidity coefficient of rock wool products is an important indicator to measure the chemical stability and durability of rock wool boards. The acidity coefficient is ≥1.8, so it has good high temperature thermal stability, durability and resistance to high temperature shrinkage.
