High-Temperature Fiberglass Tadpole Tape - Product Introduction
High-temperature fiberglass tadpole tape is a high-temperature-resistant sealing and insulation product with a distinctive "tadpole-shaped" cross-section - a round rope-like bulb on one end and a flat tape tail on the other. It is manufactured by stitching glass fiber bulky yarn or fabric around a glass fiber rope core, and is specifically designed to solve sealing problems at bolted connections, uneven surfaces, and irregular transition points where ordinary flat tapes struggle to provide an effective seal.
Core Parameters and Common Types
Product performance depends primarily on material and construction. Typical specifications are as follows:
Temperature Resistance: Standard products are rated for 450°C to 550°C. Products using special stitching techniques (such as dry stitching) or specific constructions can be rated for higher temperatures (e.g., 1000°F/538°C or above).
Dimensions: Thickness typically ranges from 3.0 mm to 5.0 mm; widths range widely from 10 mm to 200 mm; the diameter of the round (bulb) section is commonly around 10 mm to 30 mm.
Common Variants:
Self-adhesive type: Backed with adhesive for easy positioning during installation.
Vermiculite/graphite-coated type: Surface coating further improves abrasion resistance or thermal insulation performance.
Wire-reinforced type: Internal reinforcement enhances tensile strength and structural stability.
Main Applications
Thanks to its unique "round head + flat tail" structure, tadpole tape is primarily used as sealing gaskets for industrial furnace doors, valves, and flanges. The round bulb fills the gap while the flat tail facilitates fixing, effectively meeting sealing requirements under low bolt pressure. It is also commonly used for thermal insulation wrapping of high-temperature pipes, sealing of fire doors and rolling shutters, and cable insulation protection.
