Silica for Oxygen Scavengers

Product Specification

Feature

Optimized porous carrier structure: Tailored pore volume and specific‑surface‑area design, serves as high‑performance carrier for oxygen‑scavenging active components such as iron powder, ascorbic acid and catalysts. Expands reaction contact area and accelerates oxygen‑removal speed, boosts total oxygen‑absorbing capacity of scavenger systems. Efficient moisture regulation function: Balanced moisture‑adsorption capability, supplies proper humidity to sustain deoxygenation reaction; meanwhile avoids excessive moisture accumulation that causes caking, deliquescence or premature failure of oxygen scavenger sachets. Excellent powder flowability & anti‑caking: Prevents agglomeration of mixed scavenger powder raw materials; guarantees free‑flow performance during blending, granulation and sachet filling processes, supports high‑speed automated packaging production. Homogeneous dispersion of active ingredients: Uniformly loads and distributes reactive substances across silica pore channels, eliminates local over‑concentration; delivers consistent oxygen‑scavenging performance across each finished sachet. High chemical inertness & low impurity level: Strictly controlled heavy‑metal and soluble‑ion content, will not trigger undesired side‑reactions; does not interfere with deoxygenation chemistry, no off‑odors or contamination risks for food‑contact applications. Broad environmental adaptability: Maintains stable physical structure under variable temperature & humidity conditions; works reliably for dry, medium‑humidity packaging scenarios for food, pharmaceutical, electronic and artifact preservation. Food‑safety compliant grades available: Meets FCC, E551, FDA 21 CFR and GB 25576 requirements; suitable for oxygen scavengers applied in food, nut, dried food, pharmaceutical packaging fields. Good formulation compatibility: Compatible with iron‑based, organic and composite oxygen‑scavenger formulas; fits both powder blending and granulation manufacturing processes. Stable batch‑to‑batch performance: Tight control over particle size, pore‑structure, moisture and whiteness indicators, secures reproducible scavenger quality for mass continuous production. Complete supporting documentation: COA, MSDS, food‑contact certificates and formulation application guidance are provided to support customer R&D tuning and scale‑up production.
