Ngaphantsi kokukhanya kwelanga kunye ne-fluorescence, iiplastiki kunye nezinye izinto ze-polymer zifumana impendulo ye-oxidation ngokuzenzekelayo phantsi kwesenzo semisebe ye-ultraviolet, ekhokelela ekuthotyweni kweepolymers kunye nokuwohloka kwembonakalo kunye neempawu zomatshini. Emva kokuba i-absorbent ye-ultraviolet yongezwa, imisebe ye-ultraviolet ene-high-energy inokukhethwa ngokukhethiweyo kwaye iguqulwe ibe amandla angenabungozi ukuba akhululwe okanye asetyenziswe. Ngenxa yeentlobo ezahlukeneyo zeepolymers, i-ultraviolet wavelengths ezithobisayo nazo zahlukile. Iintlobo ezahlukeneyo zokufunxa i-ultraviolet zinokufunxa imitha ye-ultraviolet ngamaza ahlukeneyo. Xa usebenzisa, i-absorber ultraviolet kufuneka ikhethwe ngokweentlobo zeepolymers.
I-Absorbers ye-UV inokwahlulwa ngokwezi ntlobo zilandelayo ngokwesakhiwo sazo semichiza: i-salicylates, i-benzones, i-benzotriazoles, i-acrylonitrile efakwe endaweni, i-triazine kunye nabanye.
