Caustic Soda / Flakes

Product Overview

Caustic soda (NaOH) is a fundamental industrial alkali. JINZHUO Chemical supplies it in two forms: liquid caustic soda (concentration 32% and 50%) and solid/flake caustic soda (NaOH ≥ 99%). Liquid caustic soda is widely used in pulp and paper production, cotton textile dyeing and finishing, bauxite processing (Bayer process), wastewater pH adjustment, and saponification reactions. Flake caustic soda is primarily used for making daily chemical soaps, textile auxiliaries, and export trade. Our liquid caustic soda is delivered by tank truck. Flake caustic soda is available in 5kg woven bags (2) or ton bags (1000kg). Products comply with GB 209 standards, and quality inspection certificates are available. We welcome inquiries from customers both domestically and internationally.
