Iron Powder for Oxygen Absorbers & Heat Packs
We supply both non-annealed and secondary-reduced iron powder grades for oxygen absorber sachets, disposable hand warmers, heat packs and related reactive formulations. Grade selection depends on reaction rate, oxygen absorption performance, heat output, operating duration, particle size distribution and packaging requirements.
Application Overview
Iron powder is used as the active iron component in oxygen absorber sachets and heat-generating formulations. In sealed packaging, controlled iron oxidation helps remove residual oxygen. In disposable hand warmers and heat packs, the oxidation reaction generates heat over the required operating period.
Both non-annealed and secondary-reduced iron powder grades can be considered for these applications. The two product groups differ in production route, chemical composition, particle structure, particle size distribution and surface activity, so final grade selection should be based on the target reaction 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.
