Description

Diglycolic Acid-1,2-Propanediol Polymer is a synthetic, water-soluble polymer derived from the condensation of diglycolic acid and 1,2-propanediol. This versatile polymer is valued for its ability to act as a chelating agent, dispersant, and scale inhibitor, making it a critical component in formulations requiring control over metal ions and mineral deposits. It is primarily utilized by industries such as water treatment, detergent manufacturing, and textile processing, where its stability and performance under various pH conditions are essential.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Serves as a builder and chelating agent to sequester calcium and magnesium ions, enhancing cleaning efficiency and preventing soap scum.
• Textile Processing: Used as a dispersant and anti-redeposition agent in dyeing and scouring baths to improve color uniformity and fabric quality.
• Pulp & Paper Manufacturing: Functions as a dispersant and chelant in bleaching processes and to control pitch and scale deposition.
• Oilfield Chemicals: Employed in scale inhibition treatments for production wells and pipelines to prevent mineral fouling.
• Personal Care Products: Incorporated into formulations as a stabilizer and chelating agent to improve product shelf-life and performance.
