1.as ib qho organic polymerization ntawm lub ntsiab antioxidant.
2. Cov txheej txheem polymer ua tau zoo antioxidant, tsuas yog siv los txo viscosity hloov thiab gel tsim.
3. Muab sijhawm ntev thermal stability, nyob rau hauv kev khaws cia thiab siv cov khoom kawg los muab kev tiv thaiv lub cev ntev ntawm cov khoom siv.
4. Nws muaj cov nyhuv zoo nrog lwm cov tshuaj tua kab mob sib xyaw.
5.Txhua cov khoom lag luam sab nraum zoov tuaj yeem siv nrog Benzotriazole ultraviolet nqus thiab thaiv amine lub teeb qia me.
Dav siv dav hauv polyethylene, polypropylene, elastosic fibers, elastives, cov roj hmab, khoom siv roj hluav taws xob thiab roj roj av.
Ib qho ntxiv npaum li cas: 0.05-1%, tus nqi tshwj xeeb yog txiav txim raws li cov neeg siv khoom thov.
Ntim hauv 20kg / 25kg hnab lossis thawv.
Khaws rau hauv qhov tsim nyog nyob rau hauv ib thaj chaw qhuav thiab zoo-ventilated hauv qab no 25 ° C kom tsis txhob sib cuag nrog cov hluav taws. Txee lub neej ntawm ob xyoos.
