Ceramic Fibre Square Braided Rope – 1260°C  High-Performance Insulation
Dense Braided Rope for Gasketing, Packing & Sealing

Ceramic Fibre Square Braided Rope is a dense, resilient insulation product manufactured from ceramic fibre yarn. It can be reinforced with E-glass, stainless steel wire, or high-temperature alloy wire for enhanced performance in demanding industrial conditions. Containing approximately 18% organic fibre that burns out at high temperatures, it may produce minor out-gassing but does not affect overall performance.
