BIOSORB® 622 is a polymeric hindered amine light stabilizer (HALS) of N-R type. It exhibits good compatibility in a wide range of polymers, with very low volatility and low migration in use, resulting in cleaner surfaces, and excellent thermal stability at normal processing temperatures.It has a low melting range that makes it effective for use in PP, PE, styrenics, unsaturated polyester, acrylic, PVC, plastisols, elastomers, adhesives, sealants and spin finishes. BIOSORB® 622 can be used in polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition BIOSORB® 622 is highly effective in polyacetals, polyamides and polyurethane applications.
