Ngaphansi kokukhanya kwelanga kanye ne-fluorescence, amapulasitiki nezinye izinto ze-polymer zithola ukusabela kwe-oxidation okuzenzakalelayo ngaphansi kwesenzo semisebe ye-ultraviolet, okuholela ekulimazeni kwama-polymers kanye nokuwohloka kokubukeka kanye nezakhiwo zemishini. Ngemva kokuba i-absorber ultraviolet ingeziwe, imisebe ye-ultraviolet enamandla amakhulu ingamuncwa ngokukhetha futhi iguqulwe ibe amandla angenabungozi okufanele akhishwe noma adliwe. Ngenxa yezinhlobo ezahlukene zama-polymers, amaza e-ultraviolet awalulazayo nawo ahlukile. Ama-absorber e-ultraviolet ahlukene angamunca imisebe ye-ultraviolet ngamaza ahlukene. Lapho usebenzisa, ama-absorber ultraviolet kufanele akhethwe ngokusho kwezinhlobo zama-polymers.
Ama-absorbers e-UV angahlukaniswa abe yizinhlobo ezilandelayo ngokuya ngesakhiwo sawo samakhemikhali: ama-salicylates, ama-benzones, i-benzotriazoles, i-acrylonitrile esikhundleni, i-triazine nabanye.
