Packaging and shipping
As a professional supplier of fine chemical raw materials and pharmaceutical intermediates, we are dedicated to providing customers with high-purity and multi-specification sodium hydroxide (commonly known as caustic soda or caustic lime) products and stable supply chain solutions. Sodium hydroxide is one of the most important basic inorganic chemical raw materials in the chemical industry and is hailed as “the teeth of industry”. Due to its extremely strong alkalinity, outstanding reactivity and hygroscopicity, it has become an indispensable core raw material in dozens of industries such as papermaking, chemical synthesis, water treatment, textiles, food processing, metallurgy and petroleum refining.
