Codsiga
Antixoidant 245 waa nooc ka mid ah antioxidant phenolic ah oo tayo sare leh oo aan sinnayn, sifooyinkeeda gaarka ahna waxay ku lug leeyihiin antioxidation hufan oo sare, isbeddel yar, iska caabinta midabaynta oksaydhka, saameyn isku-dhafan oo muhiim ah oo leh antioxidant kaaliyaha ah (sida monothioester iyo phosphite ester), iyo bixinta alaabada iska caabin wanaagsan oo cimilada ah marka loo isticmaalo xasiliyeyaasha iftiinka. Antioxidant 245 waxaa inta badan loo isticmaalaa hab-raac iyo xasilin muddo dheer ah oo loogu talagalay polymer-ka styrene sida HIPS, ABS, MBS, iyo injineernimada thermoplastics sida POM iyo PA, halka ay sidoo kale u adeegto sidii joojinta dhammaadka silsiladda polymerization-ka PVC. Intaa waxaa dheer, badeecadu wax saameyn ah kuma lahan falgallada polymer-ka. Marka loo isticmaalo HIPS iyo PVC, waxaa lagu dari karaa monomers ka hor polymerization.
