  90% Purity Potassium Hydroxide (CAS 1310‑58‑3) is an essential strong alkaline chemical raw material in modern industrial production, renowned for high purity, strong alkalinity and stable chemical performance. Our export-standard KOH is refined through advanced alkaline purification process, maintaining KOH content above 90% and strictly limiting various impurity indicators. The uniform white flaky solid features pure texture, low insoluble substances and stable quality, avoiding impurity interference in industrial reactions and fully meeting international industrial production and export standards.

  This high-performance potassium hydroxide has excellent physical and chemical properties, including fast water solubility, strong hygroscopicity and superior neutralization capacity. It can quickly ionize hydroxide ions in water, providing stable and powerful alkaline environment for industrial reactions. As a versatile industrial alkali, it undertakes multiple core functions: it acts as a key raw material for potassium salt synthesis, participates in saponification and esterification reactions in fine chemical production, and serves as an efficient pH regulator for industrial wastewater treatment to neutralize acidic sewage and meet discharge standards. In textile processing, it is used for fabric desizing and mercerizing treatment; in electroplating industry, it adjusts plating solution alkalinity to optimize coating quality; in pharmaceutical and daily chemical manufacturing, it assists in raw material refining and formula synthesis.

  Different from low-purity alkaline products, our 90% potassium hydroxide features low impurity content, stable reaction efficiency and less by-product generation, effectively reducing production costs and improving finished product quality. With wide industry adaptability and reliable safety performance, it has become the preferred alkaline raw material for global industrial enterprises. All products pass strict batch testing to ensure stable indicators and qualified quality. Supported by sufficient inventory and mature global logistics system, we provide stable bulk export supply, customized packaging and professional technical support for global chemical distributors and industrial processing factories.
