Quartz Fiber Twisted Yarn is crafted from continuous high-purity quartz filaments (SiO2 content ≥ 99.95%) with a filament diameter of 7-9µm, assembled into strands and processed with varying levels of twist and ply. This material boasts superb properties including high temperature resistance, ablation resistance, low heat conduction, anti-thermal shock capability, excellent dielectric properties, and chemical stability. It finds applications in industrial furnace linings, high temperature seals, cables, filtration in aggressive environments, thermocouple insulation, satellite thermal protection, automotive exhaust insulation, radomes, electromagnetic windows, and stealth materials for aerospace and defense usage.
Quartz fiber has exceptional heat resistance and can withstand temperatures up to 1100° C (2012° F) without significant loss in mechanical properties. This makes it suitable for applications in high-temperature environments, such as furnace insulation and aerospace components.
Quartz fiber exhibits excellent resistance to a wide range of chemicals, including acids, alkalis, and organic solvents. It is unaffected by most corrosive substances, making it a reliable choice for applications in chemical processing, laboratory equipment, and harsh industrial environments.
Quartz fiber has a very low coenjcient of thermal expansion, meaning it expands and contracts minimally with temperature changes. This characteristic makes it dimensionally stable even in extreme temperature variations, making it useful for applications where thermal stability is essential, such as optical fiber communication systems and precision instruments.
Quartz fiber is a non-conductive material, providing excellent electrical insulation properties. It has low dielectric constant and loss tangents, making it suitable for high-frequency applications, such as telecom cables, electric insulation, and electronic components.
