Hello everyone! Welcome to visit our website.
Caustic soda is one of the most widely consumed basic chemicals in global industry. Our company supplies high-purity caustic soda manufactured by professional facilities under strict quality control. Customers worldwide rely on us for stable supply, safe packaging, and competitive pricing for long-term partnership.
We supply caustic soda in three commercial formats, each suitable for different industrial requirements:
Caustic Soda Flakes - 99% min
Caustic Soda Pearls - 99% min
Caustic Soda Liquid - 32%, 48% or 50%
Each production batch is tested for purity, heavy metal content, moisture percentage, and insoluble matter to ensure consistency and compliance with international industrial standards.
Due to its chemical behavior, caustic soda should be handled using proper protective gear (gloves, goggles, ventilation) and stored in sealed moisture-proof packaging.
Industrial Applications
Caustic soda plays a critical role in:
1. Paper & Pulp Industry
Used for lignin removal and cellulose fiber purification during pulp production.
2. Petroleum Refining
Applied in desulfurization, acid removal, and neutralization processes.
