Light Stabilizer UV 622 is a type of polymeric high-molecular-weight hindered amine light stabilizer, featuring a large molecular weight, low migration, good compatibility, low volatility, excellent extractability resistance, and high light stability. It is suitable for polyethylene, polypropylene, polyurethane, polyamide, polyformaldehyde, polystyrene, polyvinyl chloride, and polyolefin copolymers. When used in combination with low-molecular-weight light stabilizers and UV absorbers, it produces an excellent synergistic effect.
Used in PP, PE, PS, ABS, PU, POM, TPE etc.
