Caustic Soda
Sodium hydroxide (NaOH), one of the most representative basic chemicals in the chemical industry, is a white crystalline solid with extremely strong hygroscopic properties. It readily absorbs moisture from the air and becomes hygroscopic. Sodium hydroxide exhibits high solubility in water, releases heat upon dissolution, and demonstrates strong alkalinity. Our SHK Group supplies high-quality industrial and food-grade sodium hydroxide continuously, offering both flake (plate) and bead (granular) forms. Thanks to its stable purity and low impurity content, we are fully capable of meeting domestic demand as well as large-volume export orders overseas.

Caustic Soda classification
Industrial-grade flake caustic soda is available in plate-like crystalline form, offering excellent cost-performance and being widely used across general industrial applications such as papermaking, textile processing, wastewater treatment, and petroleum refining. It features stable dissolution rates and superior fieldwork usability.
Industrial-grade soda ash beads are spherical granules with very low dust, making them safe and convenient to handle. They are suitable for applications requiring high quality control, such as precision chemistry, resin processing, and electroplating degreasing.
Food additive grade: strictly controlled for heavy metals and harmful substances. A high-quality product that meets food additive standards. It is safe for use in the food industry, including konjac, noodles, seafood processing, and food container cleaning.
Caustic Soda Application Scenarios
Paper and pulp industry: alkalis for pulping, bleaching, and decolorization processes
Textile and dyeing industry: fabric refining, silt processing, dyeing auxiliaries, wastewater pH adjustment
Water treatment and environmental systems: neutralization of acidic wastewater, heavy metal coagulation, resin regeneration, boiler water adjustment
Detergent and personal care industry: oil sulfonation, cleaning agent raw materials, degreasing aids
Metallurgy and aluminum industry: alumina refining, steel desulfurization, impurity removal
Food processing sector: food pH adjustment, ingredient processing, sanitary cleaning (food-grade only)
