Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate CAS 52829-07-9
ʻO ka māmā stabilizer 770 he keʻokeʻo a i ʻole ka melemele crystalline pauka, kahi huahana haʻahaʻa haʻahaʻa haʻahaʻa ma waena o nā mea hoʻokūpaʻa māmā amine. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, ethyl acetate, benzene, a hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He ʻano hōʻike ia o ke kaumaha molekala haʻahaʻa HALS. Loaʻa iā ia ka photostability kiʻekiʻe a kūpono i nā huahana e like me ka polyethylene, polypropylene, polystyrene, ABS, etc. ʻO kāna hopena photostability he 3-4 mau manawa o ka ultraviolet absorbers a me ka nickel quenchers, ʻoi loa i nā huahana polyolefin. Ma muli o kona liʻiliʻi liʻiliʻi liʻiliʻi molecular paona, kiʻekiʻe volatility, kū'ē maikaʻi i ka neʻe a me ka unuhi ʻana, kūpono ia no ka hoʻohana ʻana i nā huahana mānoanoa.

ʻO Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate ka mea kūpono no ka polypropylene, polyethylene kiʻekiʻe kiʻekiʻe, polyurethane, polystyrene, ABS resin, a me nā mea ʻē aʻe. Ke hoʻohana pū ʻia me nā antioxidants, hiki iā ia ke hoʻomaikaʻi i ka pale ʻana i ka wela, a i ka wā i hoʻohana ʻia me ka hui pū ʻana me nā UV absorbers, loaʻa pū kekahi hopena synergistic, hoʻonui hou i ka hopena photostability. Hoʻohana ʻia ʻo Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate no ka polypropylene, polyethylene unsaturated resin kiʻekiʻe, polyurethane, polystyrene, a me ABS resin, a ʻoi aku ka maikaʻi o kāna hopena photostability ma mua o nā stabilizer māmā.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
