Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate CAS 52829-07-9
Light stabilizer 770 ndi ufa wonyezimira wonyezimira kapena wachikasu pang'ono, womwe ndi chinthu chotsika kwambiri cha maselo pakati pa ambiri omwe amalepheretsa kuwala kwa amine. Imasungunuka mu zosungunulira za organic monga ethanol, ethyl acetate, benzene, komanso osasungunuka m'madzi. Ndi nthumwi zosiyanasiyana otsika molecular kulemera HALS. Iwo ali photostability mkulu ndi oyenera mankhwala monga polyethylene, polypropylene, polystyrene, ABS, etc. zotsatira zake photostability ndi 3-4 nthawi ultraviolet absorbers ndi faifi tambala quenchers, makamaka polyolefin mankhwala. Chifukwa chake chaching'ono wachibale maselo, kusakhazikika kwambiri, osauka kukana kuyenda ndi m'zigawo, ndi oyenera ntchito wandiweyani mankhwala.

Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate ndi yoyenera polypropylene, polyethylene yapamwamba kwambiri, polyurethane, polystyrene, ABS resin, ndi zina zotero. Ikagwiritsidwa ntchito limodzi ndi ma antioxidants, imatha kusintha kukana kutentha, ndipo ikagwiritsidwa ntchito limodzi ndi zotsekemera za UV, imakhalanso ndi synergistic effect, kupititsa patsogolo mphamvu ya photostability. Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate imagwiritsidwa ntchito popanga polypropylene, polyethylene unsaturated resin, polyurethane, polystyrene, ndi utomoni wa ABS, ndipo zotsatira zake za photostability ndizopambana kuposa zowunikira zomwe zimagwiritsidwa ntchito nthawi zambiri.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
