Thermion-AR
200 °C continuous service, and effectively zero creep.
12-Strand Single BraidAramid Splice 95%
Schematic — 12 strands, braided in pairs
12-strand Technora® aramid under a heat-reflective jacket. Where HMPE softens and creeps, it holds its strength and its length for years at temperature.
When to specify this
The fibre of record for hot work: steel mill service, foundry rigging, refinery lifts. Also where dimensional stability beats strength per pound.
Engineering notes
- 200 °C continuous, 250 °C intermittent service temperature
- Near-zero creep. Dimensionally stable under permanent load
- Jacketed as standard. Bare aramid is not UV-serviceable
- Does not melt. Chars rather than parting suddenly under flame

Typical applications
Specifications
Minimum break strength is the value we publish and test to — not an average, and not a working load. Divide by your design factor before putting a number on a drawing.
| Diameter | Min. break strength (lb) | Weight (lb/100 ft) |
|---|---|---|
| 3/8" | 13,800 | 4.4 |
| 1/2" | 24,000 | 7.8 |
| 5/8" | 37,000 | 12.1 |
| 3/4" | 52,500 | 17.3 |
| 1" | 89,000 | 30.2 |
| 1-1/4" | 135,000 | 47 |
Working load shown at a 5:1 design factor for illustration only. Use the load calculator to apply the design factor, sling angle and termination efficiency your application actually requires.
Weights are nominal and vary ±5% with finish and coating. Elongation measured on new rope after bedding-in; expect higher values on the first cycle. Splice efficiency assumes a correctly made splice with the specified bury length.
Load against elongation
Measured to 30% of MBS. Beyond that the curve is extrapolated from the fibre, and drawn dashed to say so.
Load vs. elongation
Thermion-AR — stretch under load
Elongation as a percentage of original length, plotted against load as a percentage of minimum break strength. Drag, or focus the plot and use the arrow keys, to read any point off the curve.

- Source
- Measured
- Solid — measured at 10, 20 and 30% of minimum break strength, interpolated with a monotone cubic so the fit cannot overshoot.
- Dashed — extrapolated to 3.6% using published Aramid elongation at break. Inferred, not measured. Do not design to it.
- Shaded — working load at a 5:1 design factor, i.e. up to 20% of MBS.
| Load (% of MBS) | Elongation (%) | Source |
|---|---|---|
| 0 | 0 | Origin |
| 10 | 0.6 | Measured |
| 20 | 1.1 | Measured |
| 30 | 1.6 | Measured |
| 100 (break) | 3.6 | Extrapolated from Aramid elongation at break |
Strength to weight
Break strength per pound of rope, across the catalogue. This is the number that decides what a two-person crew can rig.
Strength-to-weight
12 ropes, ranked highest first
STRENGTH-TO-WEIGHT — LB PER LB/100 FT
Break strength divided by weight per 100 ft, best size in each range. Numerically this is breaking length in hundreds of feet — the length of rope whose own weight equals its break strength.
