Kugwiritsa ntchito
Antixoidant 245 ndi mtundu wa antioxidant ya phenolic yogwira ntchito bwino kwambiri, ndipo mawonekedwe ake apadera amaphatikizapo antioxidation yogwira ntchito bwino, kusinthasintha kochepa, kukana utoto wa okosijeni, mphamvu yogwirizana kwambiri ndi antioxidant yothandizira (monga monothioester ndi phosphite ester), komanso kupatsa zinthu kukana bwino nyengo zikagwiritsidwa ntchito ndi zokhazikika zopepuka. Antioxidant 245 imagwiritsidwa ntchito makamaka ngati njira yokhazikika komanso yokhazikika kwa nthawi yayitali ya styrene polymer monga HIPS, ABS, MBS, ndi mainjiniya a thermoplastics monga POM ndi PA, pomwe imagwiranso ntchito ngati choletsa cha unyolo mu polymerization ya PVC. Kuphatikiza apo, mankhwalawa alibe mphamvu pa zochita za polymer. Akagwiritsidwa ntchito pa HIPS ndi PVC, amatha kuwonjezeredwa mu monomers musanapangidwe polymerization.
