Brief Introduction of Glass Wool
Glass wool is made of natural ores such as quartz sand, dolomite, feldspar, limestone and so on, which are melted into glass fluid by adding in accessories such as calcined soda and borax and then drawn, blown or thrown into very thin fibers by external force under fusing state and now it is a kind of insulation material with excellent characters.

Main Materials to Produce Glass Wool

Item Description
Quartz sand Its main composition is SiO2, content of which is more than 90%
Feldspar It can be classified into potash feldspar albite according to its chemical composition. Al2O3>15%, SiO2<70%,
Fe2O3<0.3%, R2O>10%
Dolomite MgO>20%, CaO<32%, Fe2O3<0.15. Dolomite is water-absorbent, so it should be stored in dry places
Calcined soda Na2CO3>98%, NaCl<1%, Na2SO4<0.1%, Fe2O3<0.1%
Borax (Na2B4O7.10H2O) B2O3>35%, Fe2O3<0.01%, Na2SO4<0.02%
Limestone CaO≥50%, Fe2O3≤0.15%
Cullet Broken and non-conforming glass products as well as glass chops made by chilling vitreous fluid in water, whether they are glass scraps produced in production or glass waste rejected in society, all can be used as raw materials for glass

Features of Glass Wool
As a kind of inorganic fiber, glass wool has the following basic characteristics:
1. Good thermal insulation performance under both high and low temperature.
2. "Statutory incombustible material" --- it neither burns, nor gives off harmful gas.
3. Uniform resilience force.
4. Excellent sound-absorption performance and noise reducing effect.
5. Low moisture absorption rate under humid conditions.
6. Low coefficient of linear expansion.
7. Low aging rate, being able to maintain the original performance after long-time use.
8. Excellent handling characteristics.
