Isithambisi se-UV
Ngaphansi kokukhanya kwelanga 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.Uma usebenzisa, ama-absorber ultraviolet kufanele akhethwe ngokuvumelana nezinhlobo zama-polymers.
Ama-absorbers e-UV angahlukaniswa ngezinhlobo ezilandelayo ngokuya ngesakhiwo sawo samakhemikhali: ama-salicylates, i-benzones, i-benzotriazoles, i-acrylonitrile esikhundleni, i-triazine nabanye.
