Luhlobo lobunzima obuphezulu bemolekyuli buthintele i-phenolic antioxidant, ehambelana kakuhle ne-resin, ukuchasana nokutsalwa, ukuguquguquka okuphantsi, ukusebenza kakuhle kweoksijini ephezulu kunye nokufakelwa kombane okulungileyo.Ifanelekile ukuzinza kwe-oksijeni yokumelana neepolymers ezahlukeneyo kunye nezinto eziphilayo, ngokukodwa nge-phosphite, i-thioester, i-benzofuranone, i-carbon radical capture agent kunye nezinye i-antioxidant encedisayo.Kwinkqubo yobushushu obuphezulu kunye nezicelo zokuxhathisa ukukhutshwa okuphezulu ukunika iimveliso ezibalaseleyo uzinzo kunye nozinzo oluhle oluhlala luhleli.
Iinkalo zesicelo ziquka i-polyolefin, i-PET kunye nezinye i-polyester ye-thermoplastic kunye ne-PBT, i-polyamide, i-styrene resin kunye nezixhobo ze-elastomer ezifana ne-polyurethane kunye ne-rubber yendalo.Ngokukodwa ifanelekile kwi-high-temperature processing ye-polyolefin (efana ne-PP, i-PE, njl.)Ukongezelela, ngenxa yokuba ayinayo ityhefu, ayingcolisi, inokugcina umbala omhle weplastiki, ngoko ingasetyenziselwa ukudibanisa nezinto zokupakisha ukutya.
Yongeza inani: ngokubanzi i-0.05% -1.0%, isixa esithile sokongeza sinqunywe ngokuhambelana novavanyo lwesicelo somthengi.
Ipakishwe kwi-20 Kg / 25 Kg kraft bag yephepha okanye ibhokisi.
Gcina ngokufanelekileyo kwiindawo ezomileyo, ezinomoya opholileyo ongaphantsi kwe-25 C ukuphepha ukudibanisa nemithombo yokutshisa.Ubomi beshelufu yiminyaka emibini
