We are the largest supplier of phosphorous acid in China. Phosphorous acid, as an important inorganic chemical raw material, has shown a wide range of application values in many fields such as pesticides, flame retardants, electroplating additives, pharmaceutical intermediates and food preservatives. In recent years, with the rapid development of China's chemical industry and the improvement of technological innovation ability, China's phosphorous acid industry has occupied a pivotal position in the global market. As one of the world's largest chemical producers, China's phosphorous acid industry has also shown a booming trend. In recent years, with the tightening of environmental protection policies and the demand for industrial upgrading, domestic phosphite production enterprises have increased technological transformation and environmental protection investment, improving production efficiency and product quality, making China's phosphite production capacity and output continue to grow. Phosphorous acid and its salts are important raw materials for pesticide synthesis, especially in the production of herbicides such as glyphosate. With the increasing demand for efficient, low-toxic and environmentally friendly pesticides in global agriculture, the market demand for phosphorous acid continues to expand. Phosphite flame retardants are widely used in plastics, textiles, electronic appliances and other fields because of their good flame retardancy and environmental protection properties. With the promotion of fire safety awareness and the increasing demand for flame retardant materials in construction, transportation and other industries, the market demand for phosphorous acid will further grow. In addition, phosphorous acid is also used in electroplating additives, pharmaceutical intermediates, food preservatives and other fields. In electroplating industry, phosphorous acid, as an important component of nickel plating brightener, can improve the brightness and corrosion resistance of the coating. In the field of medicine, phosphite and its derivatives are used in the synthesis of a variety of drug intermediates; In the food industry, phosphorous acid is used as a preservative to extend the shelf life of food.
