Twisted ceramic fiber rope for high-temperature sealing, gasketing, and expansion joint packing up to 1260℃.
Made from high-quality ceramic fiber yarn twisted into strong, flexible rope with various reinforcement options including fiberglass or stainless steel wire.
Ceramic fiber rope is a twisted or braided cord of ceramic-fibre yarn (with optional fibreglass or stainless-steel-wire reinforcement) used for sealing, gasketing and expansion-joint packing up to refractory temperatures.

ceramic fiber bulk — Loose bulk fibre supplied for filling cavities and expansion joints, and as the raw material for vacuum-formed shapes and ceramic fibre textiles.
ceramic fiber special shaped — Vacuum-formed shapes produced to your drawing, so burner blocks, ladle covers and complex furnace geometries arrive ready to fit.
high density calcium silicate board — Ultra-high density board above 500 kg/m³ for applications where the insulation also has to carry mechanical load.

Ceramic fiber insulation withstands temperatures from 1100°C to 1430°C, depending on the grade. Standard (ST) and High-Purity (HP) grades are rated for 1260°C, while High-Alumina (HA) handles 1360°C and Zirconia (HZ) reaches 1430°C. Always match the grade to your specific operating temperature.
The grades differ mainly in alumina (Al₂O₃) content and temperature rating. COM (1100°C) is the economy grade. ST (1260°C) is the standard industrial grade. HP (1260°C) offers higher purity with lower shot content. HA (1360°C) has higher alumina for superior thermal stability. HZ (1430°C) contains zirconia for the highest temperature resistance.
Yes. Our ceramic fiber products are 100% asbestos-free and manufactured to international safety standards. They are classified as non-carcinogenic under EU Directive 97/69/EC. We recommend standard PPE (gloves, dust mask) during handling, as with any fibrous insulation material.
Ceramic fiber blanket can be cut to size with a utility knife and secured using high-temperature anchors, pins, or stud welding. For furnace linings, a layered installation is recommended. For pipe insulation, wrap and secure with stainless steel bands. Full installation guidance and technical support are provided with every order.
Ceramic fiber is widely used in industrial furnaces, kilns, boilers, petrochemical heaters, power generation equipment, incinerators, and building fire protection systems. It is ideal for backup insulation, expansion joints, door seals, and high-temperature gaskets.
