Achieving pristine whiteness and vibrant clarity in plastics and fibers requires sophisticated chemical solutions. NINGBO INNO PHARMCHEM CO.,LTD. offers Optical Brightener OB (CAS 7128-64-5), a state-of-the-art fluorescent whitening agent designed to deliver unparalleled purity and brightness for a diverse range of materials.

Unlike traditional bleaching methods that chemically alter a material to remove color, Optical Brightener OB operates on a physical principle. It absorbs invisible ultraviolet (UV) light and re-emits it in the visible blue spectrum. This re-emitted blue light neutralizes any inherent yellowness, making the material appear significantly whiter and brighter to the human eye. This is particularly effective for chemical fibers and plastics that naturally exhibit a yellowish tint or tend to yellow over time due to environmental factors.

Our Optical Brightener OB boasts an outstanding high temperature resistance and excellent weather resistance, making it ideal for applications requiring robust processing conditions, such as the extrusion of plastic films or the high-heat treatment of polyester fibers. Its consistent performance ensures long-lasting whiteness, enhancing the durability and aesthetic appeal of the final product.

NINGBO INNO PHARMCHEM CO.,LTD. is a leading optical brightener supplier for fibers and plastics, offering solutions that meet the stringent quality demands of modern industries. Whether it's to enhance the visual appeal of polypropylene fibers, improve the brightness of rigid PVC, or ensure the longevity of high-performance plastics, our chemical whitening solutions provide a reliable and efficient answer.
