Tono
Ko te Antixoidant 245 he momo antioxidant phenolic asymmetrical tino whai hua, ā, ko ōna āhuatanga motuhake ko te antioxidant tino whai hua, te iti o te hurihuri, te ātete ki te tae oxidation, te pānga mahi tahi me te antioxidant āwhina (pēnei i te monothioester me te phosphite ester), me te whakarato i te ātete pai ki te huarere ina whakamahia me ngā whakaū mārama. Ko te antioxidant 245 e whakamahia ana hei tukanga me te whakaū roa mō te polymer styrene pēnei i te HIPS, ABS, MBS, me ngā thermoplastics hangarau pēnei i te POM me te PA, ā, e mahi ana hoki hei aukati mutunga o te mekameka i roto i te polymerization PVC. Hei tāpiri, kāore he pānga o te hua ki ngā tauhohenga polymer. Ina whakamahia mō te HIPS me te PVC, ka taea te tāpiri ki roto i ngā monomers i mua i te polymerization.
