SUNLIGHT® 944 is a hindered amine light stabilizer (HALS) of the oligomeric type (equivalent to Tinuvin® 944/Chimassorb® 944), providing exceptional long-term UV light stability and thermal oxidative protection for polyolefins, polyurethanes, and engineering plastics in outdoor applications. Its polymeric structure imparts low volatility and excellent durability in demanding weathering conditions. SUNCHEM supports international buyers with SUNLIGHT® 944 sourcing from qualified Chinese producers, with quality documentation, export coordination, and logistics support.
