Product features and applications
1. HALS-622 is a polymeric hindered amine light stabilizer that is effective in a variety of polymers and applications. It is suitable for PE materials (injection molding, rotational molding, film materials and tapes), EVA, PP fibers, polyurethane, and polyacetal. , elastomers, adhesives and seals, etc. This product has a good light stabilizing effect on materials containing carbon black systems.
2. HALS-622 has low volatility, low migration, and good compatibility with materials; in pigmented materials, its application effect is better than that of ultraviolet absorbers; it can also improve the thermal and oxidative aging resistance of materials.
Recommended dosage
Typical addition levels of HALS-622 are between 0.05-1.5%.
