UV‑3431 Blue Light Absorber for Engineering Plastics
UV‑3431 is a specialized blue light absorber developed for engineering plastics that require high thermal stability during processing. It offers strong absorption in the blue light region and supports extended service life in high‑stress outdoor applications.
With low migration and high compatibility with PC, PMMA, PET, and polycarbonate alloys, UV‑3431 helps maintain mechanical strength and visual appearance under prolonged sunlight exposure.
- Excellent thermal stability for injection molding
- Low migration and blooming in finished products
- Strong blue light filtering performance
- Good solubility in polymer melts
- Supports high transparency and low haze
