2–(2’–Hydroxy–3’–tert–butyl–5’–methylphenyl)–5–chlorobenzotriazoles CAS NO.3896-11-5

UV absorber has a wide range of indirect food approvals in polylyolefins. It has a low volatility at high temperatures and high resistance to thermal degradation and can therefore be used without significant loss or decomposition in the polyolefin compounding and molding processes. In the use for the UV protection of Polyester resins, JRsorb 326 does not form colored complexes with the metallic salts used for the curing process of these resins.
