Let`s briefly talk about the characteristics and functions of medium Glass Mat

Medium Glass Mat refers to a Glass Mat with an alkali metal oxide content between 11.9% and 16.4%. Because of its high alkali content, it cannot be used as an electrical insulation material, but its chemical stability and strength are good.

There are many ways to classify medium Glass Mat. Classification based on glass raw material composition is a commonly used method at present, and it is mainly used for the classification of continuous Glass Mat. Distinguished by different alkali gold oxide contents, alkali metal oxides generally refer to sodium oxide, potassium oxide, and are introduced from soda ash, mirabilite, feldspar and other substances.
Alkali metal oxide is one of the main components of ordinary glass, and its main function is to lower the melting point of glass. However, the higher the content of alkali metal oxides in glass, its chemical stability, electrical insulation properties and strength will decrease accordingly. Therefore, glass components with different alkali contents should be used for Glass Mat with different uses. Therefore, the alkali content of the Fiber Glass composition is often used as a sign to distinguish continuous Glass Mat for different uses.
Medium Fiber Glass is widely used in wall reinforcement, (internal) and external wall insulation, roof waterproofing, etc. It can also be used to reinforce wall materials such as cement, plastic, asphalt, marble, mosaic, etc. It is an interesting engineering material for construction work. .
Glass Mat plays an important planning role in the insulation system, mainly preventing the occurrence of gaps. Because of its exquisite acid and alkali resistance and high tensile strength, it can evenly disperse the stress borne by the external wall insulation system. It has the function of soft "rebar" to prevent the deformation of the entire insulation plan caused by the impact of external forces.
