Product features and applications
1. HALS-944 is a polymeric hindered amine light stabilizer (HALS) that is effective in a variety of polymers and applications. It is suitable for PE materials (injection molding, film materials and tapes), PP materials (injection molding, film materials and fibers) , TPO, polyurethane fiber, flexible and rigid PVC, styrene, TPE, special adhesives. Also suitable for xylene cross-linked low density polyethylene.
2. As a polymeric high molecular weight hindered amine light stabilizer, HALS-944 has excellent compatibility with resin and extraction resistance, and can be used in systems requiring low volatility and small migration. Especially suitable for use in films and fibers. Low volatility, anti-migration, widely applicable to food contact materials.
Recommended dosage
Typical addition levels of HALS-944 are between 0.05-1.5%.
