Biosorb 783

Blend of poly((6-((1,1.3.3-tetramethylbutyl)amino)-s-triazine-2,4-diyl)(t-(2,2,6,6-tetramethyl-4-piperidyl)iminohexamethylene((2,2,6,6 tetramethyl-4-piperidyl)imino)) and dimethyl succinate polymer with 4-hydroxy 2,2,6,6-tetramethyl-1-piperidineethan. Is a blend of lower molecular weight and higher molecular weight HALS to optimize short as well as long term protection of the polymer. Can be used at levels not possible with other conventional HALS. The synergism between the two high molecular weight HALS components is an effective stabilization systems for the polymer against degradation through UV radiation and long term heat exposure. Can also be used in polyolefins, Olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
