Molecular Formula: FeSO?·H?O CAS: 7782-63-0 Appearance: Grayish-white powder Grade: Industrial grade, Feed grade Content: Ferrous sulfate content ≥ 90.0%, Iron (Fe) content ≥ 30.0% Usage: Feed-grade ferrous sulfate monohydrate is a mineral additive used to supplement the iron required for the growth of poultry and livestock, promoting animal development. The granular product is a popular fertilizer abroad, effectively improving soil, removing moss and lichen, and also serving as a pesticide to control diseases in wheat and fruit trees. It can also be used as a fertilizer, acting as a catalyst for chlorophyll production in plants and playing a crucial role in plant growth. Packaging: 25 kg/bag In the formulation of the isocyanate reaction: DMP-30 is a moderately active catalyst used in larger quantities in the formulation, resulting in a mild reaction, steady temperature rise, and good fluidity. The resulting product exhibits PIR high-temperature resistance/flame retardancy and can be used in the preparation of composite materials. Quality Indicators: 1. Appearance: Light yellow to brown transparent liquid 2. Amine value: 600–630 mg KOH/g 3. Relative density: 0.970–0.990 (25°C) 4. Moisture: ≤ 0.1% Physicochemical Properties: Transparent viscous liquid ranging from light yellow to pale red, soluble in organic solvents and cold water.
