Cords
Soft-core design
Flexible form
Reliable thermal barrier
Flexible cords with soft ceramic or basalt core and braided high-temperature jacket.
Over-braided cords combine a compressible fiber core—typically made of ceramic wool or basalt—with a protective braided sheath made of various high-temperature yarns. This structure ensures excellent thermal insulation, low heat conductivity, and outstanding flexibility under load.
One of the key applications of these cords is their use as impact dampers between kiln cars in tunnel kilns. Installed along the contact edges, they absorb shocks and vibrations as the cars move through the firing chamber, reducing mechanical stress and preventing structural damage during high-temperature operation.
In addition, over-braided cords are used for sealing furnace doors, inspection hatches, and expansion joints where flexibility and temperature resistance are essential. Their proven performance under thermal cycling, chemical exposure, and mechanical pressure makes them a reliable solution for harsh industrial environments—including metallurgy, power generation, and refractory systems.
OVER-BRAID Product Line
Explore the complete range of Over-Braided Cords designed for thermal insulation, shock absorption, and industrial sealing. Instead of conventional specification tables, we provide key performance indicators in the form of intuitive diagrams — allowing you to compare materials at a glance and choose the most suitable cord for your specific operating conditions.
Below are the available models of Over-Braided Cords, each listed with their key technical characteristics:
composition, core type, continuous and short-term temperature resistance, thermal conductivity, ignition loss, and available cross-sectional profiles. This format enables quick technical comparison and helps you select the most appropriate cord for thermal insulation, sealing, or impact damping in high-temperature environments.

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.
