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 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.

4, the specification of rock wool blanket
SN | Length (+10/-5mm) |
Width (+10/-5mm) |
Thickness (+10/-3mm) |
Density (±15% kg/m3) |
1 | 3000~5000 | 600 or 630 | 30 | 80~100 |
2 | 3000~5000 | 600 or 630 | 40 | 70~100 |
3 | 3000~5000 | 600 or 630 | 50 | 60~100 |
4 | 3000~5000 | 600 or 630 | 60 | 50~100 |
5 | 3000~5000 | 600 or 630 | 70 | 50~79 |
6 | 3000 | 600 or 630 | 70 | 80~100 |
7 | 3000 | 600 or 630 | 80 | 40~90 |
8 | 3000 | 600 or 630 | 90 | 40~90 |
9 | 3000 | 600 or 630 | 100 | 40~90 |
10 | 3000 | 600 or 630 | 110 | 40~70 |
When the thickness is 80mm-110mm and the density is 81kg/m3-90kg/m3, the rockwool blanket must have to be stitched with wire mesh. Otherwise, it will be broke when packed. |
