Sodium Hydroxide 25% Technical Grade

Sodium Hydroxide 25% – Technical Grade

Sodium Hydroxide (NaOH), also known as caustic soda, is a strong, corrosive alkali widely used in industrial manufacturing, water treatment, and chemical processing. Supplied as a 25% aqueous solution, it offers a balance between powerful reactivity and easier handling compared to higher concentrations. This clear, pale liquid is highly soluble in water and other polar solvents, making it suitable for a wide range of neutralization, cleaning, and synthesis applications.

Applications:

Industrial Chemical Manufacturing:
Used in producing organic and inorganic compounds, sodium hydroxide plays a key role in pH adjustment, neutralization, and chemical synthesis across multiple manufacturing sectors.

Water and Wastewater Treatment:
Applied to raise pH, neutralize acidic waste streams, and precipitate heavy metals prior to filtration and discharge.

Metal Surface Preparation:
Effective for degreasing, etching, and cleaning ferrous and non-ferrous metals, removing oxides and contaminants before coating or plating.

Pulp and Paper Industry:
Used in pulping, bleaching, and lignin removal processes, helping improve product quality and processing efficiency.

Textile Processing:
Supports scouring and mercerizing processes, enhancing dye uptake and improving fabric strength.

Industrial Cleaning:
Removes oils, grease, and organic deposits from equipment, tanks, and pipelines in manufacturing and processing plants.

Laboratory and Research Applications:
Provides a reliable alkaline medium for titrations, chemical synthesis, and analytical testing.
