Oceanchem Group LS 791

Light stabilizer 791 is a synergistic mixture of Light stabilizer 944 and Light stabilizer 770. It is an excellent UV stabilizer especially for PP thick sections, which offers excellent surface protection. It also shows high stabilization efficiency in PP tapes. Light stabilizer 791 areas of application are PP, PP/EPDM and PP/PE/EPDM blend (TPO’s). Light stabilizer 791 is an excellent UV stabilizer for thick sections.The synergism between the high and low molecular weight HALS components of Light stabilizer 791guarantees maximum protection for the polymer against degradation from UV radiation and long‐term heat exposure.
