Caustic Soda Flakes

About This Product
Caustic Soda Flakes are technical-grade sodium hydroxide (NaOH 99.0% min) in flake form, sharing the same high-purity specification as our pearls: low carbonate, low chloride and iron below 50 ppm. Flakes are the economical choice for batch dissolution and are a staple of heavy-duty cleaning compounds, effluent neutralisation, pulp and paper processing, textile treatment and general alkali duty across the process industries. The material is EU and UK REACH registered and produced in an ISO 9001 / ISO 14001 certified plant. As a Class 8 corrosive (UN 1823) it must be handled with appropriate PPE and stored dry.
