Caustic soda is the basicl raw materials along with soda ash, sulforic acid, nitrate acid and hydrocloric acid in almost all industries worldwide. As a natural co-product of chlorine production, this essential alkaline chemical is officially named sodium hydroxide. Generally, there are two forms available for heavy industrial applications: caustic soda liquid and caustic soda solid. For easy handling and transport on long distance, caustic soda solid include caustic soda pearls and caustic soda flakes.
Tianjin Jiahengyuan is proud to be one of the most reliable caustic soda manufacturers in China. Our factory has more than 25 years history in the chemical industrial sector, and for our group, Quality is the first. We do not just sell products, we deliver total peace of mind directly to your warehouse.

Our Manufacturing Capabilities:

Application:
Caustic soda is widely used in soap making, mining, water treatment, dyeing in textile industry, printing, bleaching, paper making, refined petroleum, metallurgy and other chemical industries. Because caustic soda has strong water absorption and deliquescence, it can also be used as an alkaline desiccant.
