UV absorber
N'okpuru ìhè anyanwụ na fluorescence, plastik na ihe ndị ọzọ polymer na-enweta mmeghachi omume oxidation na-akpaghị aka n'okpuru mmetụta nke ụzarị ultraviolet, nke na-eduga ná mmebi nke polymers na mmebi nke ọdịdị na akụrụngwa. Mgbe agbakwunyere ultraviolet absorber, ọkụ ọkụ ultraviolet nke nwere ike dị elu nwere ike ịhọrọ nke ọma wee ghọọ ike na-adịghị emerụ ahụ ka ewepụtara ma ọ bụ rie ya. N'ihi ụdị dị iche iche nke polymers, ultraviolet wavelengths na-eweda ha dị iche iche.
