Isicelo
I-Antixoidant 245 iwuhlobo lwe-asymmetric phenolic antioxidant esebenza kahle kakhulu, futhi izici zayo ezikhethekile zibandakanya i-antioxidation esebenza kahle kakhulu, ukuguquguquka okuphansi, ukumelana nombala we-oxidation, umphumela obalulekile we-synergistic nomsizi we-antioxidant (njenge-monothioester ne-phosphite ester), kanye nokunikeza imikhiqizo isimo sezulu esihle. ukumelana uma isetshenziswa nezinzinzisi zokukhanya. I-Antioxidant 245 isetshenziswa kakhulu njengenqubo kanye nokuqiniswa kwesikhathi eside kwe-styrene polymer efana ne-HIPS, ABS, MBS, kanye ne-thermoplastics yobunjiniyela njenge-POM ne-PA, kuyilapho isebenza njengesivimbo sokugcina seketango ku-polymerization ye-PVC. Ngaphezu kwalokho, umkhiqizo awunawo umthelela ekuphenduleni kwe-polymer. Uma isetshenziselwa i-HIPS ne-PVC, ingangezwa kuma-monomers ngaphambi kwe-polymerization.
Ukupakisha nokugcina
Ukupakisha: 25kg / isikhwama
Isitoreji: Izinzile endaweni. Asikho isidingo esikhethekile kodwa ugcine umoya futhi kude namanzi nokushisa okuphezulu.
