UV-3346 with CAS 82451-48-7
UV-3346 is a substance that improves the light stability of polymer materials. It can shield ultraviolet light waves and reduce the transmission of ultraviolet rays; or it can strongly absorb high-energy ultraviolet rays (wavelength 290-400μm), convert energy, and release energy in the form of heat energy or harmless light of longer wavelength; or it can quickly quench the excited state of high-resolution sub-electrons that have been excited by ultraviolet rays and return to a stable ground state; or it can very effectively capture free radicals generated by polymers caused by ultraviolet light, thereby protecting polymer materials from damage by ultraviolet rays. In addition to protecting polymer materials, light stabilizers can also be used to protect packaged materials from damage by ultraviolet rays, and can be used as necessary components in filters.
