Description

Chemical Name Butanedioic acid, dimethylester, polymer with *-hydroxy *2, 2, 6, *-tetramethyl**-piperidine ethanol. CAS Number *********0 Structure YS **2 Molecular Weight Mn = ***0 - ***0 Applications YS **2 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition YS **2 is highly effective in polyacetals, polyamides and polyurethane applications. Features / Benefits The effectiveness of YS **2 surpasses significantly that of UV absorbers, particularly in pigmented systems. Combinations of YS **2 with UV absorbers. Characterization YS　**2　is the light stabilizer of choice for all applications calling for low volatility and minimal migration, because of its oligomeric structure with high molecular weight. Furthermore YS **2 is effective as antioxidant and contributes significantly to the long term heat stability of polyolefins and tackifier resins. Physical and Chemical Properties Appearance and behaviour White to slightly yellow crystal powder, odorless
