FAQ – Frequently Asked Questions

Q1: What is the difference between caustic soda flakes, pearls, and liquid?
A1: Caustic soda flakes are thin, flat particles that dissolve moderately fast and are cost-effective for most industrial applications. Caustic soda pearls (or prills) are spherical, dust-free, and dissolve slightly faster but are more expensive. Liquid caustic soda (50% solution) is ready to use but requires specialized storage tanks and is less concentrated. Flakes offer the best balance of cost, handling convenience, and shelf stability for most manufacturers. NaOH Flakes price today

Q2: How should caustic soda flakes be handled safely?
A2: Caustic soda is highly corrosive and causes severe burns to skin, eyes, and respiratory tract. Always wear appropriate PPE including chemical-resistant gloves, safety goggles or face shield, and protective clothing. Use in well-ventilated areas or under exhaust ventilation. Never add water to caustic soda — always add flakes slowly to cold water while stirring. In case of skin contact, rinse immediately with plenty of water for at least 15 minutes. We provide detailed Safety Data Sheets (SDS) with every shipment. Caustic Soda Flakes price per ton

Full container loads (25 metric tons per 20ft container) receive maximum discount. Caustic Soda 99% price

Q5: How should caustic soda flakes be stored?
A5: Store in original tightly sealed bags or containers in a cool, dry, well-ventilated area away from moisture and humidity. Keep away from acids, aluminum, organic materials, and reactive metals (zinc, tin). Do not store on concrete floors without pallets. Ideal storage temperature is 15-30°C. Protect from direct sunlight. Shelf life is 12-24 months when stored properly — flakes may cake if exposed to humidity. Always reseal partially used bags immediately to prevent moisture absorption. 99% Caustic Soda Flakes
