[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.

Applications/Examples of results
■ Recommended Uses - Medical heat sheets (for products requiring protection against low-temperature burns) - High-end disposable heat packs (products designed to prevent powder leakage) - Insulation materials for transportation (for food and pharmaceuticals) - Experimental and research development (for evaluating heat generation characteristics) ■ Differences from Conventional Products Conventional iron powder (containing -100 mesh) has a lot of fine particles, which leads to issues such as rapid heat generation and powder leakage. This product is composed solely of coarse particles, fundamentally resolving these problems.
Company information
Guided by our core concept, “Unleashing the Potential of Chemistry, One Step at a Time,” we are a chemical manufacturer that addresses social and industrial challenges through ideas that go beyond conventional frameworks. We develop and manufacture chemical products such as resin putties and adhesives that cure at room temperature within 30 minutes. Starting from our customers’ voices—“We want a product like this”—we pursue solution-oriented product development and co-create new value together. At the same time, we respond to challenges such as “Our facilities are outdated” or “We lack the manpower to continue production” through our contract manufacturing service, “Tsuzukeru OEM.” From raw material procurement to final shipment, we handle the entire manufacturing process, including small-lot production starting from 40 kg. No capital investment or additional staffing is required. We help our customers continue their manufacturing and protect their brands. Furthermore, we actively promote open innovation and cross-industry collaboration. Our engineers work closely with customers on-site—thinking together and creating together. That is the kind of chemical manufacturer we strive to be.
