Caustic Soda

A versatile, highly alkaline solution used for pH adjustment, neutralisation, cleaning and chemical processing across a wide range of industries.

Overview

Caustic soda (sodium hydroxide) is one of the most widely used industrial chemicals globally. It serves as a core feedstock and processing aid in the manufacture of dyes, solvents, plastics, synthetic fibres and other chemical intermediates.

Its strong alkalinity makes it essential for water treatment, pulp and paper production, industrial cleaning, aluminium production, petroleum refining, textile processing and pharmaceutical production.
