Streamline your international chemical procurement by sourcing premium caustic soda flakes directly from our chlor-alkali manufacturing complex (annual capacity of 120,000 metric tons). Formulated specifically for industrial reactors demanding rapid aqueous dissolution and high chemical reactivity, our production delivers guaranteed purity , zero heavy metal contamination, and direct factory pricing without broker markups.
Situated just 15 kilometers from the container terminals of Tianjin Port, our facility ensures accelerated inland transport, priority export customs clearance, and prompt 20ft full container load (FCL) dispatch to major industrial hubs worldwide.

Technical Specifications (Ionic Membrane Process)
Our factory focuses on producing high-quality solid caustic soda, with two main types: caustic soda pearls and caustic soda flakes. We adhere to strict production standards, using advanced ionic membrane equipment to ensure stable product quality:

Among our products, the Premium caustic soda flakes with a minimum purity of 99% is a star product. This high-quality chemical is widely used in industrial cleaning, water treatment, textile processing, and also in the production of soap, detergents and other daily chemical products. Each batch is tested strictly before leaving the factory, ensuring that it meets industrial-grade standards.

Export-Grade Packaging and FCL Maritime Optimization
Because solid sodium hydroxide is strongly hygroscopic, our ocean packaging lines incorporate multi-layer sealing technology built to endure harsh maritime environments:
● Heavy-Duty 25kg PP/PE Woven Bags: Outer bags made of high-density woven polypropylene for tear resistance, reinforced with an independent virgin polyethylene inner bag heat-sealed against sea air and humidity.
● Maximized 28 Metric Ton Payload per 20ft FCL: Our container loading plans maximize the allowable net payload up to 28 metric tons per 20ft container (1,120 bags of 25kg), drastically reducing ocean freight costs per landed ton.
Produced using advanced ion-exchange membrane electrolysis, our solid flakes offer immediate processing benefits across diverse chemical operations:
● Instant Reaction Velocity: The flat, thin geometry expands the liquid contact surface, cutting batch mixing time in detergent formulation, pulp processing, and water treatment tanks.
● Heavy Metal Elimination: Extremely low trace impurities prevent unwanted side reactions, solution cloudiness, or premature degradation in high-end chemical synthesis.
