Light stabilizers are additives used in polymer materials that can effectively prevent photo-oxidative degradation, extend the material's service life, and are widely used in plastics, rubber, coatings, and synthetic fibers. Photoinitiators, sometimes selected as a UV initiator for UV-curable systems, are compounds that absorb light radiation energy and initiate polymerization reactions. We export highly efficient and stable light stabilizers and photoinitiators and provide research-grade compatibility recommendations.
