Hydrophilic Masterbatch is carefully developed to solve the problem that traditional polymer materials are highly hydrophobic and difficult to be compatible with water - based systems. Its core goal is to endow various plastic products and fiber materials with efficient and long - lasting hydrophilic properties while ensuring that the original physical and mechanical properties of the materials are not damaged, meeting the strict requirements of industries such as healthcare, textiles, and packaging for material hydrophilicity and comprehensive performance. This masterbatch usually selects resins with good compatibility with the target substrate as the carrier. For example, in the PP (polypropylene) system, homopolymer PP with excellent fluidity and a melt flow rate (MFR) in the range of 15 - 25g/10min is often chosen as the carrier. This can achieve efficient integration with homopolymer PP, copolymer PP, and various modified PP substrates, effectively avoiding problems such as delamination and interfacial defects caused by the incompatibility between the carrier and the substrate, and ensuring a smooth processing process.
The core value of this hydrophilic masterbatch lies in the efficient and long - lasting hydrophilicity and the non - destructive maintenance of the comprehensive performance of the substrate. For products added with hydrophilic masterbatch, the surface contact angle can be quickly reduced to less than 60°, and in some products, it can even be as low as about 30°, showing super - hydrophilic characteristics.
In terms of application scenarios, hydrophilic masterbatch widely covers the demand for material hydrophilicity in multiple fields. In the healthcare field, it is used to manufacture disposable medical protective clothing, surgical gowns, and the water - absorbing layer of the inner layer of masks. Hydrophilicity can quickly absorb human sweat and secretions, keep the wearer dry and comfortable, and help block bacteria and viruses, improving the protection effect. In the textile industry, it is used to produce sportswear and outdoor functional fabrics, enabling the fabrics to have a rapid moisture - absorption and sweat - wicking function. During exercise, sweat can be quickly absorbed by the fabric and transferred to the outer layer for evaporation, keeping the body dry and improving the wearing experience.
