The new functional masterbatch breaks the limitations of traditional single functional additives and achieves "multi effect integration" through composite formula design, which means that one masterbatch has multiple special properties and can accurately adapt to different plastic processing technologies and industry needs, becoming an important driving force for the upgrading of the plastic industry. For example, UV resistant and toughening composite functional masterbatch, with the addition of UV absorbers, antioxidants, and elastic toughening components, is suitable for outdoor injection molded parts (such as outdoor furniture, car exterior parts), blow molded products (such as outdoor water tanks, garbage cans), and pipes (such as municipal drainage pipes). It can resist aging and fading caused by UV irradiation, improve the impact resistance of products, and solve the problem of brittle cracking of outdoor plastic products; Antibacterial and anti-static functional masterbatch, which combines silver ion antibacterial agents and permanent anti-static agents, is suitable for injection molded casings, packaging films, and plastic parts in contact with food in the electronics industry (such as supermarket shopping bags and food turnover boxes). It can inhibit bacterial growth, ensure safe use, and avoid electrostatic adsorption of dust, ensuring the cleanliness of electronic components and food. In segmented industries, the application of functional masterbatch is more precise: in the medical field, antibacterial and radiation resistant functional masterbatch is used for injection molding production of medical device casings and disposable infusion sets, which can meet the sterile requirements and radiation disinfection needs of medical environments; In the field of new energy, flame retardant and thermal conductive masterbatch is used for injection molding battery shells and pipes, which can improve the flame retardant level and heat dissipation performance of products, ensuring safe use; In the packaging field, fresh-keeping and puncture resistant masterbatch is used for roll pressing films, which can extend the shelf life of food and enhance the tear resistance of the film. In addition, the new functional masterbatch also supports customized development, and the formula can be adjusted according to the specific needs of the enterprise (such as special environmental tolerance, exclusive performance combination). It is compatible with various processes such as injection molding, blow molding, roll pressing, and pipe materials, without the need to adjust production equipment, providing personalized solutions for enterprises and promoting the development of plastic products towards high-performance and multifunctional directions.
