Glass fiber is primarily used as electrical insulation material, industrial filtration material, and as anti-corrosion, moisture-proof, heat-insulating, sound-insulating, and vibration-damping materials. It can also serve as a reinforcing material for manufacturing reinforced plastics, reinforced rubbers, reinforced plaster, and reinforced cement products. Coating glass fiber with organic materials enhances its flexibility, making it suitable for packaging fabrics, window screens, wall coverings, coverings, protective clothing, and electrical and sound-insulating materials. As a reinforcing material, glass fiber possesses the following characteristics, which make its use far more widespread and rapidly developing compared to other types of fibers.

The following features are listed:

High tensile strength, low elongation (3%).

High elasticity coefficient, excellent rigidity.

(3) High elongation within the elastic limit and high tensile strength, hence it can absorb a large amount of impact energy.

(4) Inorganic fiber, flame-retardant, and has excellent chemical resistance.

(5) Low water absorbency.

(6) Excellent dimensional stability and heat resistance.

(7) Excellent for processing, available in various forms such as strands, bundles, felts, and woven fabrics.

(8) Transparent to light.

(9) Development of surface treatment agents with excellent adhesion to resins completed.

(10) Price is competitive.

(11) Non-flammable; melts into glass-like beads under high temperatures.
