[Sample available] Coarse iron powder *For measures against powder leakage in hand warmers, etc.

99.5% coarse particles that do not leak from non-woven fabric. Suppresses rapid heat generation from fine powder, achieving stable heat generation over a long period. Ideal for heat packs and thermal materials.

This is a coarse iron powder that solves the "powder leakage complaints" and "difficulty in heat control" faced by warm material and heat pack manufacturers. 【Challenges Addressed】 ✓ Complaints arise from fine powder leaking from non-woven fabric ✓ Rapid heat generation makes temperature control difficult ✓ High purity is required, but large quantities are unnecessary 【Three Features】 1. Coarse particles 99.5% (+100 mesh) → Significantly reduces the risk of powder leakage from non-woven fabric 2. Controlled heat release → No fine powder means a milder oxidation reaction, providing steady heat over a long period 3. High purity (C≦0.02%) → Few impurities, resulting in stable heat generation characteristics As it is a recycled resource produced from the manufacturing process, the annual supply is limited. It can accommodate small lots and is ideal for prototyping and research and development. Please feel free to contact us if you need samples.
