2,2,6,6-Tetramethyl-4-piperidinol CAS 2403-88-5
2,2,6,6-Tetramethyl-4-piperidinol ndi ufa wa crystalline woyera kutentha kwa firiji, kusungunuka mu zosungunulira za organic monga acetone, ethanol, ndi chloroform, kusungunuka pang'ono m'madzi, ndipo kumakhala ndi hygroscopicity. Ilinso ndi photostability ndipo imakhala ndi ntchito zofunika pazamankhwala. Zolepheretsa kuwala kwa amine ndizomwe zimagwiritsidwa ntchito kwambiri polima zinthu zolimbitsa thupi, ndipo ndi gulu la organic amine mankhwala okhala ndi steric hindrance

2,2,6,6-Tetramethyl-4-piperidinol imagwiritsidwa ntchito ngati njira yayikulu yolepheretsa kuwala kwa amine ndi kaphatikizidwe ka zolepheretsa kuwala kwa amine. Itha kugwiritsidwanso ntchito ngati chapakati chofunikira pazamankhwala, ma bleaching agents, epoxy resin crosslinkers, ndi zinthu zina. 2,2,6,6-Tetramethyl-4-piperidinol pakali pano ndi stabilizer yomwe ikukula mofulumira kwambiri yomwe imagwiritsidwa ntchito poletsa kukalamba kwa zipangizo za polima monga mapulasitiki ndi mphira.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
