Short description

This advanced thermal protection sleeve is engineered from high-purity silica fiber containing over 96% silicon dioxide, delivering outstanding resistance to extreme temperatures and harsh industrial environments. With a continuous operating range up to +982°C and the ability to withstand peaks of +1650°C, it ensures reliable performance even under the most demanding conditions. The material’s inherent flame resistance, combined with its flexibility and minimal shrinkage, makes it an ideal solution for safeguarding sensitive components in high-heat applications. Its robust chemical resistance—excluding only hydrofluoric acid, phosphoric acid, and strong bases—further enhances durability across diverse industries. The sleeve also provides excellent electroinsulating properties, ensuring both thermal and electrical protection without releasing smoke or fumes, even in direct flame exposure. With a wall thickness of approximately 1.65 mm, it offers a perfect balance of strength and adaptability, making it suitable for use in power generation, metallurgy, automotive, aerospace, and other sectors where safety and reliability are paramount. This high-performance sleeve is the ultimate choice for professionals seeking long-lasting, maintenance-free thermal insulation that guarantees maximum protection and efficiency.
