At NINGBO INNO PHARMCHEM CO.,LTD., we believe that a deep understanding of material science is fundamental to pharmaceutical success. Our pharmaceutical grade polyacrylic resin II/III is engineered to meet the rigorous demands of drug formulation, and understanding its key specifications is paramount for optimal performance. This article aims to shed light on what makes our polyacrylic resin a superior choice for your needs.

The core of our polyacrylic resin's functionality lies in its chemical makeup – a copolymer of polyacrylic acid and methacrylic acid. The precise ratio and molecular weight distribution of these monomers, reflected in the polyacrylic acid methacrylic acid copolymer specifications, dictate its behavior in various applications. For instance, its enteric-soluble coating capabilities are directly linked to its pH-dependent solubility. Our resin is engineered to be insoluble in the stomach's acidic environment (typically pH 1.5-3.5) but readily soluble in the intestinal fluid (pH 5.5-7.0). This predictable dissolution is crucial for drugs requiring targeted release.

Key parameters such as viscosity, acid value, and loss on drying are meticulously controlled. The viscosity of our polyacrylic resin, measured in mPa.s at 25°C, is kept within tight limits (e.g., ≤50 for CP Polyacrylic Resin II), ensuring consistent application characteristics whether used as an enteric soluble coating material or as a film forming agent for capsule shells. The acid value provides insights into the carboxylic acid group content, influencing the resin's solubility and interaction with other formulation components. Minimizing loss on drying (<5.0%) ensures the purity and stability of the powder form.

Furthermore, compliance with pharmacopoeial standards (USP, BP, EP, CP) for parameters like arsenic and heavy metals is non-negotiable. These rigorous quality controls guarantee that our polyacrylic resin is safe for pharmaceutical use, whether in tablets, pills, granules, or capsule shells. When you choose to buy our pharmaceutical grade polyacrylic resin, you are investing in a product backed by stringent quality assurance and a commitment to advancing drug delivery systems.
