Optical Brightener Masterbatches
Optical brightener masterbatches are plastic additives that are used to improve the brightness and whiteness of plastic products. They are often used in products that require a high level of visual appeal, such as packaging, toys, and household goods.
Optical brightener masterbatches contain optical brightening agents (OBAs), which are chemicals that absorb UV light and re-emit it as visible light. This helps to improve the perceived brightness and whiteness of the plastic, making it appear more attractive and appealing.
These masterbatches are used in order to:
• Mask natural yellowing of plastics
• Improve initial colour
• Get brilliancy of colored articles
Suggested applications are:
• Films & Sheets
• Fibers
• Molded Thermoplastic
