Unitechem HALS 119
Unitechem HALS 119 (Light Stabilizer 119) is a non-polymeric, high-molecular-weight hindered amine light stabilizer. It interacts less with agrochemicals, pigments and fillers than standard HALS and stays effective in weakly acidic environments, so it suits agricultural film, talc-filled PP and TPO automotive parts, as well as PP fibers and tapes.

Key Features
|
Non-polymeric high molecular weight HALS — unique structure combining high MW benefits with easy processing dispersibility |
Effective in weakly acidic environments — reduced interaction with agrochemicals, pigments and fillers |
|
Low volatility and migration resistance — high temperature resistance suitable for demanding processing conditions |
Outstanding thermal oxidative stability — especially in talc-filled PP and TPO automotive applications |
|
Enhances coloration of pigmented polyolefin products; compatible with a broad range of polymer systems |
Food contact approved — approved as light/thermal stabilizer in olefin polymers for food contact use |
Applications
LS-119 is especially suited for PE agricultural greenhouse films, PP fibers, talc-filled PP, and TPO automotive parts. It can also be used in EVA, EPDM, PA, PET, PMMA and powder coatings. Its unique chemical structure ensures excellent performance even in weakly acidic environments where conventional HALS may be deactivated by agrochemical residues.
