UV-988 Tetraethyl 2,2'-(1,4-phenylenedimethylidyne)bismalonate CAS 6337-43-5

UV-988 is a high absorption UV absorber developed for transparent polymer materials. It can effectively absorb the UV band sensitive to PC/PET/PMMA materials in the UVB band, reduce the damage of UV rays to the substrate, enable the material to cope with various weather conditions, and maintain good optical and physical properties even after long-term use. Furthermore, it extends the service life of solar panels and films to achieve the goal of aging resistance.
