Isicelo
I-Antixoidant 245 uhlobo lwe-antioxidant ye-phenolic engasebenzi kahle kakhulu, futhi izici zayo ezikhethekile zifaka phakathi i-antioxidation esebenza kahle kakhulu, ukuguquguquka okuphansi, ukumelana nombala we-oxidation, umphumela obalulekile wokubambisana ne-antioxidant esekelayo (njenge-monothioester ne-phosphite ester), kanye nokunikeza imikhiqizo ukumelana okuhle kokuguquguquka uma isetshenziswa neziqinisi zokukhanya. I-Antioxidant 245 isetshenziswa kakhulu njengenqubo kanye nesiqinisi sesikhathi eside se-styrene polymer njenge-HIPS, i-ABS, i-MBS, kanye ne-thermoplastics yobunjiniyela njenge-POM ne-PA, kuyilapho isebenza njengesivikelo sokugcina seketanga ku-PVC polymerization. Ngaphezu kwalokho, umkhiqizo awunawo umthelela ekusabeleni kwe-polymer. Uma isetshenziselwa i-HIPS ne-PVC, ingafakwa kuma-monomers ngaphambi kwe-polymerization.
Ukupakisha nokugcina
Ukupakisha: 25kg/isikhwama
Indawo Yokugcina: Izinzile endaweni. Akukho mfuneko ekhethekile kodwa gcina umoya ungena futhi kude namanzi kanye nokushisa okuphezulu.
