The plastics industry continually seeks innovative solutions to enhance the visual appeal and quality of its products. Optical Brightener OB, with its CAS number 7128-64-5, represents a significant advancement in this quest, offering unparalleled whiteness and brightness to a wide range of polymers. This advanced fluorescent whitening agent functions by converting invisible UV light into visible blue light, effectively counteracting the inherent yellowish tint often found in virgin plastics or developed during high-temperature processing operations.


As an experienced optical brightening agent for plastics manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. understands the unique challenges faced by polymer producers. Our Optical Brightener OB is designed for seamless integration into various plastic formulations, including polyvinyl chloride (PVC), polypropylene (PP), and polyester fiber. Its excellent solubility in common organic solvents ensures easy dispersion and uniform brightening throughout the material, contributing to consistent product quality. This ease of use, combined with its profound whitening effect, makes it an indispensable additive for modern plastic production.


A key advantage of Optical Brightener OB is its remarkable durability. It exhibits high heat & weather resistance, crucial for plastics exposed to various environmental conditions and high processing temperatures. This stability ensures that the desired whiteness and brightness are retained over the product's lifespan, preventing premature yellowing and degradation of appearance. Furthermore, its highly efficient nature means a low dosage effectiveness is typically sufficient to achieve significant improvements, making it a cost-effective solution for large-scale manufacturing operations.


Sustainability is at the core of our offerings. NINGBO INNO PHARMCHEM CO.,LTD.'s Optical Brightener OB is an eco-friendly optical brightener OB, rigorously tested and confirmed to comply with environmental standards such as RoHS and SVHC. This commitment allows plastic manufacturers to not only create visually superior products but also adhere to stringent environmental regulations and meet consumer demands for greener materials. By choosing our high-performance product, plastic manufacturers can secure a competitive edge, delivering products with truly superior whiteness & brightness that stand out in the market.
