                    Introduction :

                     YS 770 is a low molecular weight hindered amine light stabilizer(HALS) that provides excellent light stability for thick sections、films and tapes in the recommended substrates , particularly in PP thick sections. It has broad compatibility and can be easily dispersed.

                    Compared to conventional UV-absorbers , the effectiveness of YS 770 is less depend on the polymer’s thickness. For this reason , the use of YS 770 also provides good light stability in materials with high specific surface, e.g. films and tapes.

                    Combined with other HALS, YS 770 could perform better effectiveness, e.g. YS 791

                    Applications :

                    YS 770 is recommended to be used in polypropylene , impact modified PP(TPO) , EPDM , polystyrene , impact polystyrene , ABS , SAN , ASA and polyurethanes and is also effective in polyamides and polyacetal.

                    Guidelines for use :

                    The recommended concentrations range between 0.1% and 0.5% , depending on the substrate , processing conditions and application. YS 770 has low toxicity. In Japan 、Canada 、America etc , YS 770 could be used in polyolefin plastic which contacts food directly. The maximum concentration is 0.5% in Japan and America and is 0.35% in Canada.

                    Handling and Safety :

                    In accordance with good industrial practice , handle with care and unnecessary personal contact. Avoid contact with eyes. Avoid release to the environment. Avoid dust formation and ignition sources. For more detailed information please refer to the material safety data sheet.
