Ceramic Fiber Textiles
Ceramic Fiber Tape
Code prefix CT
Ceramic fiber tape is a much narrower cloth slit from the same ceramic fiber woven fabric, so its temperature class, chemistry and reinforcement are completely identical. The difference lies in handling: a narrow tape can wrap a thermocouple line or a small branch without cutting a full roll, while a wide tape covers a flange face in just two passes. Because the tape is thin, it serves as a wrapping material rather than a standalone barrier.

Working condition suitability and restrictions
Different reinforcement materials of this product correspond to different continuous use temperatures. 1260°C is only the short-term tolerance temperature; long-term over-temperature operation is prohibited. The product can only withstand short-term splashing of molten aluminum and zinc, and cannot withstand continuous erosion or immersion by molten metal.
Usage precautions
- Cutting, processing, and installation of ceramic fiber material generate fiber dust. Maintain ventilation during operation, wear dust-proof protective equipment, and dispose of waste in accordance with local environmental regulations.
- The product contains a small amount of organic fiber. Initial high-temperature use may produce carbonization and smoking, which is a normal process characteristic and does not affect product performance.
- Use temperature should be matched according to reinforcement material. Over-temperature and over-working-condition use are strictly prohibited.
- During use, regularly inspect product condition. In case of powdering, damage, shrinkage, or failure, replace promptly.
- All technical data are for reference only. Actual performance depends on usage conditions. Users should conduct their own suitability testing and comply with relevant safety regulations and standards.
02 — Characteristics
Same cloth, different width
Slitting keeps the yarn, weave and reinforcement unchanged, so a tape specification can be lifted straight onto a roll order.
Layered wrapping
Two or three overlapping passes are normal where the surface is hot and access is tight; single-pass tape is a separator, not insulation.
Glass or wire
Glass reinforced tape suits dielectric wrapping; wire reinforced tape suits joints that see pulling and abrasion.

05 — Where it is used
- Flange and valve wrapping
- Thermocouple and instrument line protection
- Pipe branch insulation
- Sealing strip in furnace doors
- Gasket facing reinforcement
Service limits
- The tape is not self-adhesive; secure the tail with stainless wire or a clip.
- Leave a small loop where the joint moves instead of wrapping tight to the metal.
- Ask for heat-cleaned tape if the part will be painted after wrapping.
