What Is Fluorescent Brightener 127?
Fluorescent Brightener 127 (also known as Optical Brightener 127) is a highly efficient whitening agent widely used in the plastics industry. It absorbs ultraviolet (UV) light and emits visible blue light, helping to reduce yellowing and enhance the whiteness and brightness of finished plastic products.
Compared with conventional whitening agents, Fluorescent Brightener 127 provides excellent thermal stability, superior compatibility with various polymers, and long-lasting whitening performance, making it an ideal choice for high-quality plastic manufacturing.
Key Features of Fluorescent Brightener 127
- Excellent whitening and brightening effect
- High thermal stability during processing
- Good compatibility with PVC and engineering plastics
- Outstanding resistance to yellowing
- Low dosage with high efficiency
- Good light and weather resistance
- Stable performance during extrusion, injection molding, and calendaring
These advantages help manufacturers improve the appearance and market value of their products while maintaining consistent production quality.
