Thermal & Warmers
Powders for air-activated heat systems and related thermal applications.
Heat output depends on controlled reactive behaviour.
Thermal systems such as air-activated warmers rely on iron powders selected for oxidation behaviour, consistency, and dependable heat generation under controlled formulation conditions. KRN supports this area through dedicated warmer-grade sponge iron and related reactive routes.
Used where the powder must generate controlled heat in an air-activated formulation, with consistency in oxidation response, output profile, and blend compatibility.
Performance priorities
What the formulation depends on here.
Controlled oxidation response
The powder needs to react in a predictable way under the intended thermal formulation.
Stable heat generation
Consistent performance matters for user experience and formulation reliability.
Blend compatibility
The selected route should fit the warmer system, packaging concept, and additive balance.
KRN grade selection
KRN grades commonly aligned to thermal systems.
These grades represent the main KRN routes considered for air-activated warmer and related reactive thermal formulations.
