Fundilizer 622 Light Stabilizers 65447-77-0 For Polyolefins / EVA Introduction Name:FUNDILIZER 622 Chemical name:Butanedioic acid, dimethylester, polymer with 4-hydroxy-2,2,6,6-tetramethyl-1-piperidine ethanol Appearance:White to pale yellow powder CAS No.: 65447-77-0 Molecular weight:2500 Description: FUNDILIZER 622 is the light stabilizer for all minimal migration and low volatility application, due to his oligomeric structure with high molecular weight. further more, FUNDILIZER 622 is effective as antioxidant and contributes significantly to the long-term heat stability of polyolefins and tackifier resins. Function: FUNDILIZER 622 is the light stabilizer for all minimal migration and low volatility application, due to his oligomeric structure with high molecular weight. further more, FUNDILIZER 622 is effective as antioxidant and contributes significantly to the long-term heat stability of polyolefins and tackifier resins. Use: polyolefins (PP,PE), olefin copolymers such as EVA ,polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and adhesive specialty applications. FUNDILIZER 622 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In additionFUNDILIZER 622is highly effective in polyacetals, polyamides and polyurethane applications.
