Disposable warmers & heat wraps
Iron powder for air-activated heat packs
Controlled-particle reduced iron for exothermic heat pack formulations.
Typical failure points
- Excess fines causing uneven or aggressive heating
- Odor from sulfur and carbon residues
- Temperature profile drifting between lots
Key specifications
| Parameter | Value |
|---|---|
| Sulfur (S) | < 0.018 % TBC |
| Carbon (C) | < 0.15 % TBC |
| Fines below 400 mesh | Strictly limited TBC |
| Heating profile | Formulation-dependent TBC |
- Note: Temperature and duration depend mainly on the full formulation (carbon, salt, water, film). Publish only with test conditions.
