Soluble Fiber Textiles
Soluble Fiber Tape
Code prefix AT
Soluble fiber tape is slit from AES cloth and supplied in standard widths from 30 mm to 150 mm and thicknesses of 2, 3 and 5 mm. Glass reinforced tape serves at 650 C, metal reinforced and sintered tape at 1000 C, and all variants take a 1200 C short excursion. It is used to wrap lines and joints where the specification excludes refractory ceramic fiber.

01 — Product description
Widths that suit the joint
AES tape is slit from soluble fiber cloth in widths from 30 mm to 150 mm and thicknesses of 2, 3 and 5 mm. Three grades are held: glass reinforced at 650 C, metal reinforced at 1000 C and sintered at 1000 C with a non-combustible finish. All take a 1200 C short excursion.
The sintered grade is the one to choose where smoke on first heat matters, because the organic content has already been burned out at the mill. It is stiffer as a result, so corners need a wider radius than the glass reinforced tape.
| Code | Thickness | Width | Grade |
|---|---|---|---|
| AT2-30 | 2 mm | 30 mm | Glass, 650 C |
| AT3-50 | 3 mm | 50 mm | Glass, 650 C |
| AT5-100 | 5 mm | 100 mm | Metal, 1000 C |
| AT3-150S | 3 mm | 150 mm | Sintered, 1000 C |
On site
- Overlap by half the width and fix the tail mechanically.
- Do not bend sintered tape sharply; it cracks along the fold.
- Keep the rolls dry until installation.
- Cut with respiratory protection and dispose of offcuts as mineral fiber waste.
02 — Characteristics
Standard widths
30, 40, 50, 60, 70, 75, 80, 100, 120 and 150 mm from stock.
Three grades
Glass reinforced, metal reinforced and sintered non-combustible.
Low smoke
The sintered grade has already had its organic content burned out.

05 — Where it is used
- Pipe and flange wrapping
- Joint sealing strips
- Cable tray protection
- Furnace door gaskets
- Transport thermal barriers
Service limits
- Sintered tape is stiffer; allow a wider bend radius at corners.
- The tape does not bond to metal and needs a mechanical fixing.
- Dust controls apply during cutting.
