Key Features
≥99.5% sulfamic acid provides a consistent active-acid concentration for industrial cleaning formulations and process control.
≤1 ppm chloride helps minimize chloride-related contamination in applications where low-halide raw materials are required.
Water-insoluble substances ≤0.02% help reduce undissolved residues during preparation and circulation of cleaning solutions.
A white crystalline form and controlled bulk density of 1.15–1.35 g/cm³ support predictable weighing, handling, and formulation.
