Glass fiber, also called fiberglass, is a non-metallic inorganic material with many advantages. It has light weight and high mechanical strength. Compared to metal materials, fiberglass has lower density, easy to handle and install, making it enable to be used in many applications where lightweight materials are required. It has high tensile strength, extrusion strength and bending strength. Fiberglass has good permeability to resins and is a composite material widely used in construction, marine, automobile, aerospace and other fields.

Glass fiber has low thermal conductivity and excellent thermal insulation property. Its thermal stability is good and it will not melt at high temperatures. It is a kind of high temperature resistant material which can be made into a range of high temperature resistant fabrics such as fiberglass cloth, fiberglass tapes, fiberglass ropes, etc.

Because glass fiber is a non-metallic material, it does not rust and corrode compared with the conventional metal materials. It is less affected by chemical corrosion and can withstand the corrosion of many acids, alkalis and salts, and has a long service life. Fiberglass is an ideal corrosion resistant material for making chemical products such as petrochemical pipelines, storage tanks, etc.

Glass fiber is an excellent electrical insulation material, which can be made into electrical and electronic components. It also can be used as insulation material for wrapping electrical motors and other electrical equipments.

Glass fiber has excellent environmental protection. It is made from waste glass and glass is a material which has no harm to human body and environment. Fiberglass will not produce toxic gases and waste water, no pollution to environment.

The production cost of glass fiber is low and the processing is relatively simple and economic. In addition, fiberglass has the advantages of low water absorption, good processability, strong plasticity, easy molding and cutting, good permeability to resins, etc. 

In summary, glass fiber has obvious advantages in high temperature resistance, light weight, high strength, corrosion resistance and electrical insulation. The advantages of glass fiber make it an ideal choice for many applications.
