In the competitive plastics industry, achieving a bright, appealing white finish is often a key differentiator. Optical Brightener OB-1 (CAS 1533-45-5) stands out as a premier fluorescent whitening agent, specifically designed to enhance the visual quality of a wide array of plastics. As a dedicated supplier and manufacturer, we understand the critical needs of plastic converters and compounders for high-performance additives. This guide aims to equip B2B buyers with the knowledge to effectively integrate OB-1 into their production processes.

Optical Brightener OB-1 is highly valued for its excellent whitening strength and strong fluorescence, which effectively masks yellowness and provides a 'whiter-than-white' appearance. Its superior thermal stability is a significant advantage, allowing it to withstand the high processing temperatures common in molding and extrusion applications for materials such as rigid PVC, ABS, PS, HIPS, PA, PC, PP, and EVA. Unlike less stable brighteners, OB-1 maintains its efficacy, ensuring consistent results across different production batches. This makes it a reliable choice for manufacturers seeking to buy high-quality plastic additives.

The recommended dosage for OB-1 in plastics typically ranges from 0.005% to 0.2% by weight of the substrate, depending on the specific polymer and the desired level of whiteness. Proper dispersion is key to achieving optimal performance, and OB-1 is easily incorporated into plastic formulations. For procurement managers and R&D scientists, understanding the value proposition is crucial. Purchasing OB-1 from a reputable manufacturer in China ensures competitive pricing and a stable supply chain.
