Product Name : Light Stabilizer **0 Low Molecular Weight Hindered Amine Light Stabilizer　(HALS) Characterization **0 is a hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surfacearea such as films and tapes. Chemical Name Bis (2, 2, 6, *-tetramethyl**-piperidyl) sebaceate CAS Number *********9 Structure **0 Molecular Weight **0.*4 Applications **0 is recommended to be used in polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact poystyrene, ABS, SAN, ASA and polyurethanes and is also effective in polyamides and polyacetals. Features / Benefits **0 is a low molecular weight hindered amine light stabilizer that provides excellent light stability for thick sections and films in the recommended substrates. Benefits of using **0 is the high light-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers, the effectiveness of **0 is less dependent on the polymer’s thickness. For this reason the use of YS **0 also provides good light stability in articles with higher specific surface, xxxxx and tapes. Combined with other HALS **0 is part of other synergistic blends, xxxxx **1 Guidelines for use The recommended concentrations range between 0.1% and 0.5%, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of **0 in various substrates and for various applications is available upon request. Physical and Chemical Properties Appearance and behaviour White crystalline powder or granules, odorless PH-value (1% suspension in water *0~*5℃) 9.*7 Melting / freezing temperature *0~*6℃ Density (*0℃)
