Unitechem HALS 944
Unitechem HALS 944 (Light Stabilizer 944) is a polymeric, high-molecular-weight hindered amine light stabilizer. Its low volatility, low migration and high extraction resistance make it the general-purpose long-term UV stabilizer for PE and PP films, tapes, fibers and molded parts, and it is often blended with HALS 622 or HALS 770.

Poly{[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidyl)imino]-1,6-hexanediyl[(2,2,6,6-tetramethyl-4-piperidyl)imino]}
Key Features
|
Polymeric, high-molecular-weight HALS with excellent low volatility |
Low migration and high extraction resistance — ideal for thin articles, fibers and films |
|
High thermal stability — stable under thermo-oxidative conditions; additional antioxidant effect |
Synergistic effect with UV absorbers (e.g., UV-770, UV-3853, LS-622) |
|
FDA approved for food contact applications (21 CFR) |
Provides long-term thermal stabilization of polymer matrices |
Applications
LS-944 is effective across a broad range of polymers: polyolefins (PE, PP), crosslinked polyethylene (XLPE), olefin copolymers (EVA), TPO, polyurethane fibers, flexible and rigid PVC, styrenic polymers, TPE, and specialty adhesives. Particularly recommended for thin-walled products, films and fibers where low migration is critical.
