Silica fiber sleeve, also commercially known as thermal sleeving or spaghetti tubing, is the ultimate solution for component protection in extreme heat environments. Manufactured with an SiO2 content exceeding 96%, it ensures structural integrity where other materials fail.
Silica thermal-resistant sleeving or spaghetti tubing is an advanced textile component renowned for its low thermal conductivity and excellent chemical stability. It is an inorganic product that does not burn and resists most acids and alkalis, making it the preferred choice for the aerospace, metallurgical, and energy sectors.
This silica fiber sleeve is an industrial-grade thermal insulator designed to encase cables, hoses, and pipes exposed to severe conditions. Thanks to its high-purity chemical composition, it offers an impenetrable barrier against radiant heat and molten metal splashes, maintaining operational flexibility even after prolonged exposure.
Given its resistance to temperatures up to 1000 degrees Celsius, this product is ideal for:
• Thermal Insulation: Sealing joints in industrial furnaces and boilers.
• Cable Protection: Covering electrical harnesses in engines and exhaust systems.
• Resin Reinforcement: Used as a base material for high-temperature resistant composites.
• Industrial Safety: Spark barrier in welding processes and protection for hydraulic hoses.
• Superior Thermal Resistance: Capable of continuous operation at 1000°C and resisting temperature peaks (softening point) close to 1700°C.
• Chemical Purity: Silicon dioxide content (SiO2 ≥96%), ensuring the material does not degrade or release toxic gases.
• Electrical Insulation: Excellent dielectric properties, ideal for preventing electrical arcs in high-power installations.
• Chemical Durability: High corrosion resistance and stability against aggressive chemical agents.
• Flexibility: Its woven structure allows for easy installation on bends, curves, and complex geometries.
Silica fiber sleeve stands out for its inorganic composition, which allows it to maintain its mechanical and insulating properties even under extreme thermal stress.
