High silica continuous yarn is meticulously processed from acid-treated and heat-treated glass fiber yarn.This specialized yarn finds versatile applications in weaving, sewing, bundling, and wrapping within high-temperature textiles. Renowned for its exceptional durability and thermal protection, it serves as a vital component in insulation, sealing, and industrial settings. From sleeves to sewing threads and electronic cigarette cores, this yarn offers reliability in demanding environments, providing effective heat resistance and insulation. It is mainly used in weaving, sewing, bundling, winding heating wires and heating elements, thermal insulation materials, seals, etc., such as casing, sewing thread, electronic cigarette cores.
High silica glass fiber is a special fiber with SiO3 content of more than 96%, which can be used at 1000°C for a long time and the instantaneous temperature can exceed 1450°C. It has excellent thermal resistance, ablation resistance, high dielectric strength, acid resistance and other properties. Widely used in the fields of fire extinguishing and rescue, new energy applications, high-temperature insulation, metal melt filtration, and other fields, especially in the military, national defense, aviation, and aerospace industries, quality can reach international advanced levels stably.
High silica glass fiber has outstanding thermal resistance. It can withstand extremely high temperatures, often exceeding 1000°C (1832°F) without significant degradation. This makes it ideal for applications where exposure to high heat is common, such as in fire protection, insulation, and aerospace industries.
This property of ablation resistance arises from its high silica content, typically exceeding 96%. This robust resistance to heat erosion makes it an ideal choice for applications where exposure to intense heat or flames is prevalent. Industries such as aerospace, automotive, construction, and manufacturing utilize high silica glass fiber in environments where thermal erosion is a concern, ensuring longevity and safety in various operational conditions.
The structure of High Silica Glass Fiber enables it to have a high dielectric strength, which is the maximum electric field that a material can withstand without experiencing electrical breakdown. This property allows it to effectively resist the flow of electrical current, making it suitable for use in high voltage applications.
High silica glass fiber demonstrates exceptional resistance to acidic environments due to high silica content, which shields the fiber from the corrosive effects of most acids. It finds extensive use in chemical processing plants, laboratories, and industrial manufacturing facilities where acids are prevalent either as part of processes or within the environment.
