1, the introduction of rock wool blanket
Rock wool blanket uses high-quality basalt as raw material whose melting point is above 1000 ºC and has good effects on heat insulation and sound absorption.
Rock wool blanket has good properties of fire resistance, pest proof, corrosion resistance, stable chemical property and do not contain asbestos. It is green environmental production and do no harm to human bodies.
2, the features of rock wool blanket
2,1 Fireproof Performance
Phenix rock-wool products take basalt and dolomites as raw materials with the melting point of over 1000 degrees centigrades. It will not release any poisonous smoke and can effectively cut off the spread of flam when fire occues.
2,2 Thermal Insulation Performance
Phenix rock-wool products has low thermal conductivity and excellent heat insulation performance because of its low shot content and spindly fibers. It can effectively reduce the heat loss of buildings to achieve energy-saving and emission-reduction.
2,3 Waterproof Performance
rock-wool products are waterproof, anti-aging and have good performance of long-term stability.
2,4 Acoustic Insulation
The theory of acoustic insulation is that the fibers is porous and connected, it can not only stop the spread of sound waves but also absorb them. The acoustic insulation performance has been widely recognized all over the word. And the density is lower, the performance is better.

4, the application of rock wool blanket
Rock wool blanket is suitable for the large pipeline, container, storage tank and boiler of thermal insulation. It can also be single -stitched with wire mesh which can make it be more fixed and strong and can not be damaged.

10 | 3000 | 600 or 630 | 110 | 40~70 |
When the thickness is 80mm-110mm and the density is 81kg/m3-90kg/m3, the rock wool blanket must have to be stitched with wire mesh. Otherwise, it will be broke when packed. |
