FR Glass fiber sewing thread

Key Characteristics

100% high-purity glass fiber core: Inherently flame-retardant and fireproof, non-combustible in open flame, self-extinguishing immediately after leaving fire, with zero melt-drip risk to eliminate secondary fire hazards.

Extreme temperature resistance: Sustains stable performance in continuous high-temperature environments up to 550°C, and resists short-term exposure to 1000°C high heat without structural damage, far exceeding aramid and polyester threads.

Superior mechanical strength: High tensile strength, low elongation, and excellent dimensional stability; not easy to break during stitching, suitable for heavy-duty sewing of thick fireproof fabrics and industrial materials.

Excellent chemical stability: Resists corrosion from most acids, alkalis, organic solvents and chemicals; immune to moisture, mildew and UV radiation, ideal for harsh industrial and outdoor scenarios.

Outstanding insulation performance: Non-conductive, with high dielectric strength, safe for sewing electrical insulation materials, high-voltage equipment covers and fire-resistant cables.

Customizable specifications: Available in various ply counts and linear densities; optional silicone coating for enhanced wear resistance and processability.

Applications

High-temperature filtration field: Sewing high-temperature filter bags (such as filter materials used in power plants and waste incineration plants).

Safety protection field: Sewing the outer layer or interlayer of fire suits, racing suits, and industrial heat insulation suits. 

Composite materials: It is used for sewing glass fiber and carbon fiber composite material components (such as pre-impregnated blanks for wind turbine blades and aerospace parts).

Industrial special fabrics: sewing high-temperature conveyor belts, flame-retardant tarpaulins, electrical insulating fabrics and more.
