Akamashini gafata UV
Mu gihe cy'izuba n'urumuri, pulasitiki n'ibindi bikoresho bya polymer bikorerwa oxidation yikora binyuze mu mirasire ya ultraviolet, ibi biganisha ku kwangirika kwa polymer no kwangirika kw'isura n'imiterere ya mekanike. Nyuma yo kongerwamo ultraviolet absorber, imirasire ya ultraviolet ifite ingufu nyinshi ishobora kwinjizwa mu buryo bwihariye igahinduka ingufu zitagize ingaruka mbi kugira ngo irekurwe cyangwa ikoreshwe. Bitewe n'ubwoko butandukanye bwa polymer, uburebure bwa ultraviolet buyingiza nabwo buratandukanye. Imirasire ya ultraviolet itandukanye ishobora kwinjizwa mu mirasire ya ultraviolet hamwe n'uburebure butandukanye. Mu gihe ikoreshwa, imirasire ya ultraviolet igomba gutoranywa hakurikijwe ubwoko bwa polymer.
Udukoresho dufata imirasire y'izuba dushobora kugabanywamo ubwoko bukurikira hakurikijwe imiterere yabyo: salicylates, benzones, benzotriazoles, acrylonitrile yasimbuwe, triazine n'izindi.
