Light Stabilizer UV 120

Light Stabilizer UV120 is a benzene acid ester photostabilizer, possessing dual functions of photostabilizer and antioxidant. It can absorb UVB and UVC, with the absorption peak at 265nm. 

It has the characteristics of high temperature resistance, resistance to extraction, low volatility, and low migration, and is suitable for PC, PET, PBT, PMMA, coatings, and inks. When used in combination with high molecular weight photostabilizers and UV absorbers, the synergistic effect is significant.It has excellent long-term thermal stability and light stability. The general dosage is 0.05-0.20%

Applications:

Used in Polypropylene (film, flat filament, injection molding), polyethylene, ABS resin, unsaturated resin, etc.
