For professionals in the paper manufacturing industry, the quest for superior paper quality is constant. One of the most critical components in achieving this is the effective use of sizing agents. Among these, aluminum sulfate stands out as a highly effective and widely adopted chemical. As a premier manufacturer and supplier of high-purity aluminum sulfate, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing paper mills with the essential materials to elevate their production standards.

Aluminum sulfate, particularly the iron-free and high-purity grades we offer, plays a pivotal role in the papermaking process. Its primary function is as a sizing agent. Sizing is a process that controls the absorption of liquids, such as ink or water, into paper. Without proper sizing, paper can become overly absorbent, leading to issues like ink feathering and poor print definition. Aluminum sulfate works by reacting with rosin, another common papermaking additive, to form aluminum rosinate. This substance precipitates onto the cellulose fibers of the paper pulp, creating a hydrophobic barrier that limits liquid penetration.

The benefits of using our high-quality aluminum sulfate are manifold. Firstly, it significantly improves the strength and formation of the paper sheet, contributing to a more robust final product. Secondly, it enhances the paper's resistance to water and ink, leading to crisper print quality and reduced waste from printing errors. For paper manufacturers looking to buy these benefits, understanding the importance of sourcing from a reliable supplier is paramount. We ensure our aluminum sulfate is manufactured to exacting standards, guaranteeing consistent performance and purity.

Moreover, the environmental profile of our products is a key consideration.
