O le polymer e masani ona i ai i se tulaga anoxic i lalo o tulaga e faʻaogaina ai le extrusion, ma o loʻo i ai i le faiga le tele o faʻamaʻi carbon nai lo le alkoxy radicals ma hydroxyl radicals.O le mea lea, e tatau ona mafai e le faʻamautu faʻatulagaina lelei ona puʻeina faʻamalosi faʻamalosi saʻoloto.O le hydroxylamine antioxidant o loʻo taʻua i luga o se ituaiga o mea e faʻapipiʻi ai le carbon radical.
Ole autu ole carbon free radical trapping agents ile maketi ole hydroxylamine, bisphenol mono-acrylate, ortho acrylyl suitulaga phenol ma benzofuranone tele vaega.
Bisphenol monoacrylate antioxidants:
I mole mole o le bisphenol monoacrylate, o le carbon radical e puʻeina e le acrylyl group, ma o le enol radicals na gaosia e mafai ona liua i faʻamaʻi okesene phenolic mautu e le hydroxyl functional group i le mole tutusa.O lenei aafiaga ua ta'ua o le bifunctional stabilization mechanism.O le mea lea e maua ai e le bisphenol monoacrylate se malosi malosi e pu'eina fa'amalosi fua.O lona faʻamautu e malosi e tusa lava pe maualuga le vevela.Kamupani i Iapani ma Europa ua faʻalauiloa ia oloa.I le taimi nei, Sumilizer GM e Sumitomo Chemical, IRGANOX 3052 e le BASF, ma le AO3352/AO3353 e masani ona faʻaaogaina i le maketi.

| FAATONUGA | Faʻaaoga lautele i PP, PE ma isi polyolefin, ABS, HIPS, EPDM, SBR ma isi elastomers. | Fa'aaoga lautele i mea fa'apipi'i, styrene thermoplastic elastomers, ABS, polystyrene ma le pa'u ua suia polyphenylethylene ma isi fanua.E mafai ona pu'eina lelei fa'alilal radicals, ma fa'atino a'afiaga fa'atasi ma benzotriazole UV absorbers ma HALS fa'amautu malamalama.I totonu o le elastomer pipii, o loʻo i ai se aafiaga lelei synergistic ma phenolic antioxidants ma phosphite ester antioxidants. |
