Fiberglass yarn is a yarn made from glass fiber. Glass fiber is an inorganic non-metallic material with the advantages of light weight, high specific strength, corrosion resistance and good insulation properties. Currently, there are two kinds of commonly used Fiberglass yarns: monofilament and multifilament.
The primary characteristic of fiberglass window screen is its long service life. Fiberglass yarn is because it has several advantages such as anti-aging, cold resistance, heat resistance, dryness and humidity resistance, flame retardant, moisture resistance, anti-static, good light transmission, no tampering, no deformation, ultraviolet resistance, high tensile strength and so on. These determine that it is not easy to be damaged under non-artificial factors, and we can use it for a long time.
1. Good use in process, low fuzz
2. Excellent linear density
3. Twists and diameters of filament depend on customers' requirements.
As fiberglass yarn has good tensile strength and higher stability, it can be used in different environments to ensure that its quality meets the standard, especially moisture-proof and heat-insulating as well as sound-insulating effect is very good, as a filtration material or vibration-damping material in the industrial industry, it shows its due characteristics and advantages in different engineering and construction.
Fiberglass yarn is mainly used as electrical insulating material, industrial filtration material, anticorrosion, moisture-proof, heat insulation, sound insulation, shock absorption material. It can also be used as reinforcing material to make reinforced plastic or reinforced gypsum and other FRP products.
Fiberglass yarn is also widely used in weaving for fiberglass weaving fabric, fiberglass mesh, belts, rope, pipes, grinding wheel, etc.
