Glass fiber cotton, quartz glass cotton

Glass wool is made by melting natural minerals such as quartz, dolomite, feldspar, limestone, etc. with auxiliary materials such as soda ash and borax to form glass liquid. In the molten state, it is drawn, blown or thrown into extremely fine fibrous materials by external force.

Glass wool is an inorganic fiber with the following basic characteristics:

① It has good thermal insulation performance under both high and low temperature conditions.

② It does not burn and does not produce harmful gases, and is recognized as a "legally non combustible material" by various countries.

③ Has uniform elastic recovery force.

④ The moisture absorption rate is low under humid conditions.

⑤ The coefficient of linear expansion is small.

⑥ The aging rate is low, and it can maintain its original performance after long-term use.

⑦ Has good processing performance.

Glass wool is a long filamentous material with good flexibility; No impurities or debris;Maximum temperature tolerance of 600 ℃, can be used for laboratory catalysis, filtration, and insulation (but has not undergone deactivation treatment and is not suitable for filling lining tubes)
