Modern paper mills are constantly seeking advanced paper sizing solutions to meet the ever-growing demands for high-quality and durable paper products. NINGBO INNO PHARMCHEM CO.,LTD. provides cutting-edge chemicals designed to push the boundaries of paper performance. Our Cationic Rosin Size LSR-35 stands as a testament to our dedication, offering superior internal sizing capabilities for a wide array of paper and paperboard applications. For manufacturers in search of a reputable cationic rosin size supplier, our product offers reliability and consistent quality.
This innovative sizing agent, characterized by its white milky emulsion for paper making, is formulated using a sophisticated high-pressure homogenization process. This results in an incredibly fine particle size, ranging from 0.6 to 0.8µm, which ensures optimal dispersion and adhesion within the paper fibers. The outcome is paper with significantly enhanced strength and water resistance, even with a remarkably low dosage rosin size for paper. This efficiency translates directly into cost savings and improved production yields for our clients.
Our Cationic Rosin Size is particularly effective for achieving high-strength paper sizing agent results across various paper grades, from cultural and special gelatin papers to newsprint and corrugated board. It functions efficiently within a broad pH range of 4.0-8.5, offering operational flexibility that many traditional sizing agents lack. If you are looking to buy cationic rosin size that delivers consistent, superior performance and contributes to the overall efficiency of your mill, NINGBO INNO PHARMCHEM CO.,LTD. is your trusted partner. We are committed to supplying chemicals that empower your production process.
