In the vast landscape of plastic manufacturing, achieving pristine whiteness and vibrant colors is key to product differentiation and market success. NINGBO INNO PHARMCHEM CO.,LTD. offers Fluorescent Brightener OB, an indispensable additive specifically formulated to optimize the aesthetics of PVC and polyolefin materials. This powerful PVC optical brightener works by converting UV light into visible blue light, effectively neutralizing the inherent yellowish tint often present in these polymers and delivering a strikingly brighter appearance.


For manufacturers working with PVC (polyvinyl chloride), polyethylene (PE), and polypropylene (PP), Fluorescent Brightener OB proves to be a game-changer. These materials are widely used in everything from pipes and films to packaging and consumer goods. The slight yellowing that can occur during processing or over time can compromise their visual quality. By incorporating Fluorescent Brightener OB, the clarity and whiteness of rigid and soft PVC products are significantly improved, making them appear cleaner and more premium. Similarly, for polyolefins, this polyolefin whitening agent ensures a brilliant white effect, crucial for transparent and brightly colored applications.


The dosage recommendations for Fluorescent Brightener OB are precise and efficient, ensuring optimal results with minimal material usage. For instance, in hard or soft PVC, brightening can be achieved with just 0.01-0.05% of the material weight, while transparent applications require even less, from 0.0001-0.001%. For polyolefins, dosages typically range from 0.0005-0.001% for transparent uses and 0.005-0.05% for brightening. This precise control allows manufacturers to fine-tune the desired level of whiteness and brilliance without over-application.


Beyond its immediate brightening effects, Fluorescent Brightener OB provides excellent long-term stability. Its superior heat and weather resistance prevent re-yellowing, ensuring that the enhanced aesthetics endure throughout the product's lifespan. This durability is especially vital for products exposed to sunlight or varying environmental conditions. As a trusted fluorescent brightener OB supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers competitive fluorescent brightener OB price for bulk purchase, alongside technical expertise to assist our clients in achieving their specific aesthetic goals.
