View MoreA brightening agent mainly acts on the surface of plastic products. During processing, it migrates to the surface and forms a thin film with a high refractive index, improving gloss and smoothness for a more attractive appearance.
During high-temperature extrusion or injection molding, strong friction between the molten resin, mold, and screw can cause flow marks, buildup, and surface roughness, leading to low brightness and difficult demolding. A plastic brightening agent helps address these issues by enhancing surface gloss, improving color dispersion, and providing internal and external lubrication, reducing scratches and drag marks.
Our product disperses quickly without agglomeration and is suitable for PVC, PE, PP, and other plastics across various processes. It remains stable during thermal processing without yellowing, making it suitable for high-temperature films and engineering plastics. With high purity and low impurities, it offers efficient migration and improved gloss with lower dosage, helping produce smoother, brighter, and more stable plastic products.
