PRODUCT OVERVIEW

Product Description

PMA Series Poly Aacrylic Acid - Maleic Acid Copolymer is a water-soluble sodium salt copolymer based on acrylic acid and maleic acid chemistry. It is used in detergent and cleaning formulations as a dispersing and processing aid. The product helps control dirt redeposition, supports calcium dispersion, provides pH-buffering performance, and improves slurry processing in detergent manufacturing. The PMA series is supplied in several molecular-weight and viscosity grades, including PMA40-55, PMA40-64, and PMA40-73, allowing selection according to the required formulation and processing characteristics.
