Products Description
Sodium hydroxide, also known as caustic soda or lye, bears the chemical formula NaOH. It is a highly corrosive strong base, generally supplied in the form of white flakes or granules. It dissolves in water to form alkaline aqueous solutions, and is also soluble in methanol and ethanol. This alkaline compound is deliquescent; it readily absorbs water vapor as well as acidic gases such as carbon dioxide from ambient air. As one of the most widely‑used industrial chemicals, sodium hydroxide covers extensive application scenarios and serves as an indispensable raw material across multiple industrial workflows. It is heavily utilized for wood‑pulp paper manufacturing, textile processing, soap and detergent production, and is also a key ingredient in household alkaline drain‑cleaning formulations.

Product Application
Sodium hydroxide (CAS 1310-73-2) is a versatile inorganic alkali with broad usage in both laboratory research and large-scale industrial manufacturing. For chemical experiments, it functions as a standard reagent and alkaline desiccant, attributed to its notable hygroscopic capacity. Within industrial markets, pharmaceutical chemical production consumes the largest volume of sodium hydroxide. Beyond this sector, the material is heavily utilized in papermaking, aluminium and tungsten metallurgy, viscose fibre and artificial cotton production, alongside soap making. It also supports the manufacturing of dyes, plastic goods, pharmaceutical compounds and organic intermediates. Other key applications involve waste rubber reprocessing, gold beneficiation, water electrolysis processes, and the synthesis of multiple inorganic salts including borax, chromates, manganates and phosphates. Different product grades follow specified national standards: industrial sodium hydroxide complies with GB209-2006, ion-exchange membrane type meets GB/T11199-89, chemical fibre grade follows GB11212-89, while food-grade sodium hydroxide conforms to GB5175-85.
