Chini ya jua na fluorescence, plastiki na vifaa vingine vya polymer hupata mmenyuko wa oxidation moja kwa moja chini ya hatua ya mionzi ya ultraviolet, ambayo inaongoza kwa uharibifu wa polima na kuzorota kwa kuonekana na mali ya mitambo. Baada ya kifyonzaji cha ultraviolet kuongezwa, mionzi ya ultraviolet yenye nguvu nyingi inaweza kufyonzwa kwa kuchagua na kugeuzwa kuwa nishati isiyo na madhara ili kutolewa au kuliwa. Kutokana na aina tofauti za polima, wavelengths ya ultraviolet ambayo huwaharibu pia ni tofauti. Vipumuaji tofauti vya ultraviolet vinaweza kunyonya mionzi ya ultraviolet na urefu tofauti wa mawimbi. Wakati wa kutumia, vichungi vya ultraviolet vinapaswa kuchaguliwa kulingana na aina za polima.
Vipumuaji vya UV vinaweza kugawanywa katika aina zifuatazo kulingana na muundo wao wa kemikali: salicylates, benzones, benzotriazoles, acrylonitrile iliyobadilishwa, triazine na wengine.
