Description

Maleic Acid-Methacrylic Acid Copolymer is a synthetic polymer formed from maleic acid and methacrylic acid monomers. This versatile copolymer is valued for its excellent film-forming, dispersing, and chelating properties, making it a critical functional additive in various industrial processes. It is primarily utilized in sectors such as pharmaceuticals, water treatment, and personal care, where its ability to control scale and modify rheology is essential.

Application

• Pharmaceutical Excipient: Used as a binder, film-coating agent, or taste-masking polymer in tablet and capsule formulations.
• Scale Inhibitor: Effective in industrial water treatment and cooling systems to prevent the deposition of calcium carbonate and other mineral scales.
• Dispersing Agent: Stabilizes suspensions and prevents agglomeration in pigments, ceramics, and detergent formulations.
• Personal Care Products: Functions as a thickener, stabilizer, or film-forming agent in hair care and skincare products.
• Textile & Leather Processing: Acts as a dye dispersant and tanning auxiliary to improve process uniformity.
• Detergent Builder: Enhances the cleaning efficiency of detergents by sequestering metal ions that cause water hardness.
