Ceramic Fiber Textiles
Ladder Fiber Tape
Code prefix TL
The ladder fiber tape family covers glass fiber, ceramic fiber and bio-soluble fiber versions, and the base material decides the basic performance of each. The ladder structure leaves openings along the tape so bolts can pass through, which is why it is fitted across flange and bolted joints to provide thermal insulation and auxiliary sealing. It is a low-pressure static material and is not a high-pressure gasket.

01 — Product description
High-Temperature Resistant Fiber Ladder Tape
Product description
High-temperature resistant fiber ladder tape includes fiberglass ladder tape, ceramic fiber ladder tape, biosoluble fiber ladder tape, and other series. The basic performance of the product is determined by the base material.
The ladder tape structure facilitates bolt passage and is suitable for flange and bolted connection locations, providing thermal insulation and auxiliary sealing functions. It is only suitable for low-pressure static conditions and cannot be used as a high-pressure sealing component.
Product specifications
| Product Code | Material | Thickness (mm) | Width (mm) | Working Temperature (°C) |
|---|---|---|---|---|
| GTLX-YY | Fiberglass | X | YY | 550°C (reference short-term tolerance temperature under static no-load conditions) |
| CTLX-YY | Ceramic fiber | X | YY | 1000°C (specific analysis required for specific conditions) |
| BTLX-YY | Biosoluble fiber | X | YY | 1000°C (specific analysis required for specific conditions) |
Note: X and YY in the table are variable specification parameters; thickness and width dimensions can be customized as needed.
Application scope
Applicable scenarios:
- Thermal insulation for industrial kilns, high-temperature pipelines, and high-temperature vessels;
- Low-pressure static thermal insulation auxiliary sealing for furnace doors, valves, and flange locations;
- High-temperature thermal insulation protection for engines and instrument equipment;
- Flue lining thermal insulation gaskets.
Packaging
30 m/roll or 50 m/roll, single-roll independent plastic bag packaging.
Usage precautions
- Cutting and grinding of ceramic fiber ladder tape generate fiber dust. During operation, wear dust masks and protective gloves, and ensure ventilation protection; biosoluble fiber products are also recommended to have dust protection. Dispose of waste in accordance with local environmental regulations.
- Product temperatures are reference working condition values. Continuous use temperatures and short-term tolerance temperatures differ among different materials. Use beyond the design temperature is strictly prohibited.
- The product can only achieve low-pressure static auxiliary sealing. Under high-pressure or high-vibration conditions, sealing failure and material damage may occur.
- During use, conduct regular inspections. In case of powdering, cracking, or damage, 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
Ladder structure
Open gaps along the tape let bolts pass through, so the tape sits across a bolted joint without being drilled or cut away.
Three base materials
Glass fiber, ceramic fiber and bio-soluble fiber; the base material sets the temperature class and the mechanical behaviour.
Flange and bolted joints
Insulation and auxiliary sealing at flanges, valves and furnace doors working at low pressure and static conditions.
Thickness and width to order
Thickness X and width YY are variable parameters; both are made to the joint rather than supplied from a fixed list.

05 — Where it is used
- Low-pressure static sealing at furnace doors, valves and flanges
- High-temperature protection for engines and instruments
- Flue liner insulation gaskets
Service limits
- Low-pressure static auxiliary sealing only: not for high pressure, liquid media, strong corrosives, high-velocity gas, heavy vibration or repeated rubbing.
- Not a high-temperature filter medium, and not recommended as direct fire-rated cable wrap.
- Cutting and grinding release fiber dust; use a dust mask and gloves with adequate ventilation.
- Temperature values are reference figures; never exceed the design temperature, and replace the tape when powdering, cracking or damage appears.
