Chemical composition: acrylic acid homopolymer

Chemical structural formula:

Performance and Applications

PR-445、PR-445N、PR-445ND It is a partially neutralized acrylic homopolymer, an environmentally friendly additive that is phosphate-free, non-toxic, and pollution-free, exhibiting excellent calcium‑magnesium chelating ability and superior calcium carbonate dispersing performance. When used as a fabric‑washing aid, a laundry‑detergent additive, or an industrial‑cleaning‑agent enhancer, this product can enhance the detergent’s resistance to soil redeposition, improve its foaming and rinsing characteristics, and also reduce slurry viscosity, while demonstrating outstanding… pH Buffering capacity, reducing the irritancy of detergents to the skin.

PR-445、PR-445N、PR-445ND It is also a highly versatile pigment and filler dispersant, widely used in inorganic additives. ( Such as calcium carbonate, titanium dioxide, barium sulfate, and talc powder. ) It is widely used in fields such as ceramics, coatings, textile printing and dyeing, and papermaking. This product can disperse a variety of powders and is particularly well suited for the grinding and dispersion of calcium carbonate and the dispersion of ceramic slurries. When employed as a grinding and dispersing agent or a slurry dispersant, it offers the advantages of low dispersion viscosity and reduced dosage; even small additions enable it to maintain a relatively low effective dispersion viscosity at high solid loadings, while also providing excellent storage stability and effectively mitigating the re‑gelling of pigments and fillers. It is suitable for a wide range of ultrafine pigments and fillers.

PR-445N It exhibits low foaming, minimizing foam formation during both manufacturing and application, and demonstrates high dispersing efficiency for mineral pigments, thereby reducing grinding and dispersion time in production and saving energy. Additionally, this chelating dispersant is widely used in the textile printing and dyeing industry, particularly in pretreatment processes, where it can significantly enhance scouring performance. In operations such as desizing, scouring, bleaching, and dyeing, it helps reduce the amount of water… Ca2+ 、 Mg2+ 、 Cu2+ 、 Fe2+ The impact of metal ions on product quality; on H2+O2+ Its decomposition provides protective effects and safeguards fibers; it can significantly enhance whiteness and eliminate yellowing.
