UV absorber
A karkashin hasken rana da haske, robobi da sauran polymer kayan sha atomatik hadawan abu da iskar shaka dauki a karkashin mataki na ultraviolet haskoki, wanda take kaiwa zuwa lalatar da polymers da tabarbarewar bayyanar da inji Properties. Bayan an ƙara abin sha na ultraviolet, za a iya ɗaukar haskoki na ultraviolet mai ƙarfi da zaɓaɓɓu kuma a juya zuwa makamashi mara lahani don fitarwa ko cinyewa. Saboda nau'ikan polymers daban-daban, tsayin raƙuman ultraviolet da ke lalata su ma sun bambanta. Daban-daban ultraviolet absorbers iya sha ultraviolet haskoki tare da daban-daban raƙuman ruwa. Lokacin amfani, yakamata a zaɓi masu ɗaukar ultraviolet bisa ga nau'ikan polymers.
Ana iya raba masu ɗaukar UV zuwa nau'ikan masu zuwa gwargwadon tsarin sinadarai: salicylates, benzones, benzotriazoles, maye gurbin acrylonitrile, triazine da sauransu.
