Properties and Usage:

Phosphorous acid is a multifunctional compound with a wide range of applications, including plastic stabilization, agricultural pesticides, water treatment, and more. The following is a detailed introduction to phosphorous acid:

1. Plastic stabilizer and nylon whitener

- Phosphorous acid is widely used in the plastics industry as a reducing agent and nylon whitening agent, helping to improve the quality and appearance of plastic products.

2. Agricultural pesticide raw materials

- As a raw material for agricultural pesticide intermediates, phosphorous acid can be used to manufacture downstream products such as phosphites. It inhibits bacteria on crops, promotes plant growth, and provides phosphorus to plants.

3. Water treatment agent

- Phosphorous acid can be used as a water treatment agent to purify drinking water and industrial water. It can effectively remove heavy metal ions, suspended solids and organic matter in water and improve water quality. Phosphorous acid can control the excessive growth of algae in water bodies, prevent the formation of algae blooms, and maintain the clarity and ecological balance of water bodies.

4. Buffer

- As a buffering agent for water bodies, phosphorous acid helps maintain the acid-base balance of water bodies and provides a suitable living environment for aquatic organisms.

Fscichem produces phosphorous acid in various specifications, among which the phosphorous acid with a slight odor is of high quality and low price, and is very popular in the international market. Whether it contains odor or whether the content is high determines the use of phosphorous acid itself. Contact technical staff for more information and MSDS
