Koresha
Iki gicuruzwa ni ikintu gitera urumuri kudahindagurika gifite imikorere myiza, gishobora kwakira imirasire ya UV ya 240-340 nm ifite imiterere y'ibara ryoroheje, ntigihumanya, gihura neza, kigenda gake, gitunganywa byoroshye n'ibindi. Gishobora kurinda polymer ku rugero rwacyo runini, kigafasha kugabanya ibara. Gishobora kandi gutinza umuhondo no kubangamira gutakaza imikorere yacyo. Gikoreshwa cyane kuri PE, PVC, PP, PS, PC organic glass, polypropylene fibre, ethylene-vinyl acetate n'ibindi. Byongeye kandi, gifite ingaruka nziza cyane ku buryo urumuri rudahindagurika ku byuma bya phenol aldehyde, varnish ya alcohol na acname, polyurethane, acrylate, expoxnamee n'ibindi.
Igipimo rusange
Igipimo cyayo ni 0.1%-0.5%.
1.Polypropylene: 0.2-0.5wt% hashingiwe ku buremere bwa polymer
