Polyacrylic Acid (CAS No. 9003-01-4) is a high-molecular-weight polymer synthesized through advanced solution polymerization using acrylic acid as the monomer. Its Chinese aliases include acrylic resin, carbomer, and Carbomer 934P. With a chemical formula of (C₃H₄O₂)ₓ and an average molecular weight of approximately 2000, it appears as a colorless viscous liquid, pale yellow liquid, or solid under certain working conditions. As a multifunctional polymer material, it boasts excellent water solubility and chemical stability. The product features high purity ranging from 99.5% to 99.9% with extremely low impurity content, and benzene residue is only 0.1%-0.5%, fully complying with industry safety standards and suitable for professional applications in various fields.
Density of 1.09 (30% aqueous solution), melting point of 106℃, boiling point of 116℃, flash point of 61.6℃, and refractive index of n20/D 1.442. It maintains stable performance under normal temperature and pressure without easy decomposition.
Easily soluble in water, it can quickly form a uniform and stable aqueous solution without complex pretreatment, adapting to different concentration preparation requirements.
Although it has certain irritancy, risks can be effectively avoided through standardized operation and protective measures. The product complies with relevant GHS classification standards, and a complete Material Safety Data Sheet (MSDS) is available in both Chinese and English.
The mainstream acrolein oxidation method is adopted to produce acrylic acid monomers, which is safe, low-pollution, and cost-effective. During the polymerization stage, precise temperature control (50-150℃) and a dedicated initiator system are employed, combined with chain transfer agents (such as mercaptosuccinic acid) and polymerization inhibitors (such as hydroquinone), ensuring uniform molecular weight distribution and high performance consistency of the product.

As a high-efficiency scale inhibitor and dispersant, it can be used in industrial circulating water treatment systems to effectively inhibit scale formation and extend equipment service life, adapting to different water quality conditions.
It can be cross-linked with cyclodextrin to prepare mucoadhesive hydrogels for controlled-release pharmaceutical preparations, improving the stability of drug release and demonstrating great application potential in solid dosage forms.
It can serve as a basic component of remodelable biomaterials in biomedical engineering such as chest wall reconstruction, providing support for tissue repair.
It can be used to produce acrylic resin-related products and act as a functional additive in industries such as coatings, adhesives, and daily chemicals, exerting thickening and dispersing effects.
1. Water treatment engineer from a chemical enterprise: "This polyacrylic acid has stable scale inhibition effect and fast dissolution rate. When prepared into a solution and added to the circulating water system, the scaling of equipment is significantly improved. Moreover, the safety technical data is complete, making operation very reassuring."
2. Biomaterial R&D personnel: "As a polymer material for experiments, it has excellent purity and performance consistency. The hydrogel prepared by cross-linking with cyclodextrin meets the expected adhesion and drug controlled-release effects, and we will continue to purchase it."
3. Logistics and transportation specialist: "The product packaging is standardized with clear transportation labels. No abnormalities occurred during transportation in accordance with dangerous goods transportation requirements, and no leakage happened during loading and unloading. The accompanying safety instructions facilitate verification in the logistics link."
