FAQ's About Optical Brightener

We can make a black masterbatch to suit your specific needs. For instance, you can ask us to add UV light to the batch, or carbon black loading, filler-free, or resin and we can adjust the batch to meet your specific requirements.

Optical Brighteners work by absorbing UV light (which is not visible to the human eye) and re-emitting it as blue light, which is visible. This blue light makes the material appear whiter and brighter to the human eye, compensating for any yellowish or dull tones in the material.

Optical Brighteners are typically not recommended for use in food packaging, as they are not considered food-safe and may not meet regulatory standards for food-contact materials. If needed, it's important to use only optical brighteners that are certified as safe for food contact and comply with FDA or EU regulations.

Optical Brighteners can be used in a wide variety of plastics, but their effectiveness may vary depending on the type of plastic, processing conditions, and the specific brightener used. Some plastics, like polypropylene or polyethylene, may require specific optical brighteners designed for compatibility with their polymer structure.

Optical Brighteners are typically incorporated into materials during the manufacturing or processing phase. In textiles, they are added during the dyeing or finishing process. In plastics, they are mixed with the polymer during extrusion or injection molding. In detergents, optical brighteners are added directly to the product formulation.
