Ceramic Fibre Braided Round Rope – 1260°C Thermal Insulation
Durable High-Temp Rope for Seals, Gaskets & Packing

Ceramic Fibre Braided Round Rope is a dense and resilient insulation material designed for extreme high-temperature sealing, gasketing, and packing applications. Braided from ceramic fibre yarn around a reinforced ceramic core, it offers long-term durability and resistance in harsh thermal environments.

Key Features

• Maximum temperature rating: continuous use up to 1260°C
• Melting point: 1760°C
• Insert temperature limits: glass 650°C, steel 1100°C
• Thermal conductivity: <0.18 W/mK at 1000°C
• Shrinkage (24 hrs): 3% at 1150°C
• Density: 480–650 kg/m³

Composition & Properties

• Chemical composition: Al₂O₃ 46%, SiO₂ 53%
• Electrical properties: ceramic fibres are non-conductive; steel reinforcement is conductive
• Colour: white
• Organic fibre content: 18% (burns out at high heat with minor out-gassing)

Ideal Applications

• Replacement for asbestos-based packing
• Radiant tube packing in heat-treatment furnaces
• Expansion joint packing in boilers and furnaces
• Seals for stoves, ovens, and industrial kilns
• High-temperature door seal insulation
