Knitted Cords
Knitted Insulation Cords for Flexible High-Temperature Sealing
Flexible cords made from heat-resistant fibers such as glass, high silica, or basalt. Manufactured using a knitted structure that ensures exceptional flexibility, good dimensional stability, and reliable performance under thermal and mechanical stress. These cords are ideal for continuous exposure to high temperatures and are commonly used for sealing furnace doors, inspection covers, hatches, and thermal expansion joints. Unlike rigid braided cords, knitted cords offer a soft, compressible structure that easily adapts to uneven, rough, or fragile surfaces — minimizing installation effort and improving sealing reliability. Suitable for demanding industrial environments such as metallurgy, power generation, and thermal processing systems. Their resilience to heat, thermal cycling, and chemical exposure makes them a dependable solution in harsh operating conditions.

Thermal Strength — The Foundation of Reliability
The resistance of fibers to high temperatures determines the performance and service life of insulation and sealing products. The chart provides a clear comparison of how glass, basalt, aramid, carbon, ceramic, and silica fibers behave under heat. This data helps identify the optimal material for applications where reliability under extreme temperatures is critical.
Technical specifications are for reference only. Actual performance may vary depending on chemical exposure, temperature shocks, and mechanical loads such as compression or friction. Values are based on ideal lab conditions — always assess real application factors before use.
