Cords
Cross-Braided Insulation Cords for High-Temperature Sealing
Flexible cords made from heat-resistant fibers such as glass, ceramic, or basalt. Manufactured with a cross-braided structure to provide uniform density, excellent dimensional stability, and enhanced mechanical strength under thermal stress. These cords are designed to withstand continuous exposure to high temperatures and are used for sealing furnace doors, inspection ports, hatches, and expansion joints. Suitable for a wide range of industrial applications including metallurgy, power generation, and thermal processing equipment. Their reliable sealing performance and resistance to heat, thermal cycling, and chemical exposure make them an ideal choice for harsh operating environments.
CROSS-BRAID - Product Line
Explore the complete range of Cross-Braid Cords designed for thermal insulation and industrial sealing. Instead of traditional property tables, we present key performance data as clear and easy-to-read diagrams — so you can easily compare different cord types and select the optimal solution for your application.
Below are the available models of Cross-Braid Cords, each listed with their key technical characteristics: composition, short-term and continuous temperature resistance, thermal conductivity, mass loss on ignition, and cross-sectional dimensions. This format enables quick technical comparison and helps you choose the most suitable cord for your thermal sealing application.

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.
