EVERSORB 91 Light Stabilizer for Polymers

Eversorb 91 is a hindered amine light stabilizer for polymers. Even with low contents of Eversorb 91 in plastic formulation, it still exhibits superior light stabilization. Eversorb 91 is particularly suitable for using in polyolefins. It is also efficient to the stabilization of polyurethanes, styrenic polymers, polyvinyl chloride and polyamides.
