Iron Powder for Oxygen Absorbers & Heat Packs
Our non-annealed iron powder grades are produced through a single reduction stage and supplied without secondary reduction or annealing. They can be considered for oxygen absorber sachets, disposable hand warmers, heat packs and related reactive formulations, with grade selection based on reaction rate, heat output, operating duration and packaging requirements.
Application Overview
Non-annealed iron powder provides the reactive iron source in oxygen absorber and heat-generating formulations. In oxygen absorber applications, iron oxidation helps remove residual oxygen from sealed packaging. In hand warmers and heat packs, controlled oxidation generates heat over a required operating period.
These grades are produced through a single reduction stage and supplied without secondary reduction or annealing. Grade selection can be reviewed according to chemical composition, particle size distribution, surface activity, reaction rate, heating profile, formulation and packaging conditions.
Key Requirements
Powder selection for oxygen absorbers and heat packs depends on the target reaction rate, oxygen absorption performance, heat output, operating duration, particle size distribution, formulation compatibility and packaging conditions.
Controlled Reaction Rate
Suitable iron powder helps support a controlled oxidation rate according to the target application, powder dosage, formulation ingredients and packaging conditions.
Heat Output & Duration
For hand warmers and heat packs, powder properties can influence heating speed, temperature profile, operating duration and overall heat consistency.
Particle Size & Surface Activity
Particle size distribution and particle morphology affect surface activity, mixing behavior, oxidation rate and contact with other formulation ingredients.
Oxygen Absorption Performance
For oxygen absorber applications, powder characteristics can influence activation speed, oxygen removal capacity and performance consistency inside sealed packaging.
Formulation Compatibility
Powder grades can be reviewed according to the carbon material, salt, moisture-retaining material and other ingredients used in oxygen absorber or heat-pack formulations.
Packaging & Shelf Stability
Final powder selection should also consider packaging permeability, storage conditions, activation behavior and the required product shelf life.
