Isifutho se-UV
Ngaphansi kokukhanya kwelanga kanye ne-fluorescence, amapulasitiki nezinye izinto ze-polymer zenza ukusabela okuzenzakalelayo kwe-oxidation ngaphansi kwesenzo semisebe ye-ultraviolet, okuholela ekuwohlokeni kwama-polymer kanye nokuwohloka kokubukeka kanye nezakhiwo zemishini. Ngemva kokuba i-ultraviolet absorber ingeziwe, imisebe ye-ultraviolet enamandla aphezulu ingamuncwa ngokukhetha futhi iguqulwe ibe amandla angenangozi ukuze ikhishwe noma idliwe. Ngenxa yezinhlobo ezahlukene zama-polymer, ubude bama-ultraviolet obuwohlokayo nabo buhlukile. Ama-ultraviolet ahlukene angakwazi ukumunca imisebe ye-ultraviolet ngama-wavelength ahlukene. Uma usebenzisa, ama-ultraviolet absorber kufanele akhethwe ngokwezinhlobo zama-polymer.
Izifutho ze-UV zingahlukaniswa ngezinhlobo ezilandelayo ngokuya ngesakhiwo sazo samakhemikhali: ama-salicylates, ama-benzones, ama-benzotriazoles, ama-acrylonitrile ashintshiwe, ama-triazine nabanye.
