Porogaramu
Antiksoidant 245 ni ubwoko bwa antioxydant ya phenolic idafite ingano, kandi umwihariko wayo urimo kurwanya oxidation ikora neza, kudahinduka cyane, kurwanya ibara rya oxidation, ingaruka zikomeye zo guhuza hamwe na antioxydant yunganira (nka monothioester na phosphite ester), no guha ibicuruzwa ubudahangarwa bwiza bwo guhangana n'ikirere iyo bikoreshejwe hamwe n'ibikoresho bitanga urumuri. Antiksoidant 245 ikoreshwa cyane cyane nk'uburyo bwo gutunganya no guhagarara igihe kirekire kuri polimeri ya styrene nka HIPS, ABS, MBS, na thermoplastics za tekinoloje nka POM na PA, mu gihe inakora nk'umugozi w'uruhererekane muri polimeri ya PVC. Byongeye kandi, ibicuruzwa nta ngaruka bigira ku bikorwa bya polimeri. Iyo bikoreshejwe kuri HIPS na PVC, bishobora kongerwa muri monomers mbere yo gupima.
