Polyvinyl Chloride (PVC) and Acrylonitrile Butadiene Styrene (ABS) are two of the most widely used plastics, found in everything from construction materials to automotive parts. While their versatility is immense, maintaining their pristine whiteness and preventing yellowing during processing or over time can be a challenge. This is where advanced additives like Fluorescent Brightener OB-2 prove invaluable, optimizing PVC and ABS manufacturing processes for superior results. NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of this essential whitening agent.


Fluorescent Brightener OB-2, a yellow-green solid, is specifically formulated to counteract the inherent yellowish tint that can develop in PVC and ABS. By absorbing UV light and emitting blue light, it optically enhances the brightness and provides a clean, vibrant white appearance. This effect is crucial for products where visual quality is paramount, such as rigid PVC pipes, window profiles, or aesthetically demanding ABS components like appliance housings. The high-purity OB-2 for ABS plastics ensures minimal interference with other material properties while delivering maximum whitening power.


One of the significant advantages of OB-2 is its exceptional heat resistance, crucial for the high processing temperatures often involved in PVC and ABS extrusion or molding. This ensures that the brightening effect remains stable and uniform throughout the manufacturing process, preventing degradation or discoloration. Furthermore, its excellent migration resistance means the brightener stays within the polymer matrix, preventing blooming or loss of effect over time, even in complex multi-layer applications. As a dedicated Fluorescent Brightener OB-2 supplier, NINGBO INNO PHARMCHEM CO.,LTD. guarantees a product that meets rigorous quality standards, ensuring stable quality batch after batch.
