Product Overview
SARbrite™ is a specialized range of optical brighteners and whiteners engineered to enhance the visual brightness, whiteness, and clarity of polymers, coatings, textiles, and paper. Developed with advanced light-conversion technology, SARbrite™ improves product appearance by absorbing UV light and re-emitting it as visible blue light—delivering a cleaner, whiter, and more brilliant finish.
Key Features
- Exceptional Whitening Effect: Produces a bright, blue-white tone that enhances product appearance.
- High Fluorescent Efficiency: Maximizes light conversion for improved optical performance with minimal dosage.
- Thermal Stability:Performs reliably in high-temperature polymer processing environments.
- UV-Activated Performance: Designed for maximum effectiveness under natural or artificial UV exposure.
- Wide Material Compatibility: Works with plastics, coatings, synthetic fibers, inks, and paper.
Applications
- Polyolefins (PP, PE) and PET plastics
- PVC profiles, films, and injection molded products
