Qiyan New Materials Launches High-Purity Guanidine Sulfamate (Assay ≥ 99.5%)

Qiyan New Materials has officially launched its high-purity guanidine sulfamate (CAS 51528-20-2) with a stable assay of ≥ 99.5% (measured 99.86%), significantly exceeding the conventional 95% grade on the market. Strict impurity control — iron ≤ 5 ppm, moisture ≤ 0.30%, water insoluble matter ≤ 0.2% — ensures stable extrusion and non-yellowing parts in PA6 compounding, where UL-94 V-0 is achieved at only ~9% loading. The product also serves flame-retardant finishing of textiles, wallpapers, carpets, curtains and wood furniture, and acts as an interfacial passivation agent for perovskite solar cells (electronic grade). Every batch is supplied with a Certificate of Analysis, with flexible packaging from 25 kg fiber drums to 800 kg jumbo bags.
