Glass Fiber

Glass Fiber

Glass fiber is obtained from quartz sand, sodium tetraborate, etc. after melting at the temperature of 1400℃. By adopting the most advanced centrifugation technology, fibration of molten glass will occur. Some binder will be added into the liquid glass, and then fiber glass blanket comes into being after solidifying and molding process. At the moment, this product has many, thin fibers and its total surface area is quite large. Air resistance increases, preventing air from heat transfer. In a similar way, huge friction greatly diminishes air vibrations. Therefore, our product gives outstanding thermal insulation and sound absorption properties.

Features and Advantages
1. Our glass fiber offers good thermal insulation properties at high temperature or low temperature as well as homogeneous elastic restoring force.
2. This product is recognized as legal non-combustible material by various countries all over the world. Also, it generates non toxic gas.
3. It is able to absorb high, medium and low frequency sounds. Noise reduction effect is quite outstanding.
4. This glass fiber gives low hygroscopicity in cold or damp weather.
5. It has small coefficient of linear expansion and low aging rates.
6. Good machinability is provided.

The above data show that glass fiber has best thermal insulation effect among these materials.

Our glass fiber offers less than 10kg/m3 apparent density. Its average fiber diameter is of within 7.6μm. Its thermal conductivity is not excess of 0.058 w/m.k below the temperature of 24 ℃. It has the features of small volume and density, low thermal conductivity, and good sound absorption properties. Apart from these features, this product is characterized by its good anti corrosion properties and superior chemical stability.
