UV-329 CAS 3147-75-9
ʻO ka UV absorber UV-329 he mea maikaʻi loa a maikaʻi hoʻi ka anti-aging agent, hiki ke hoʻoheheʻe ʻia i loko o ka benzene, styrene, ethyl acetate, hiki ke hoʻoheheʻe ʻia i ka ethanol, insoluble i ka wai, hiki ke komo i ka 270-340 nm UV kukui, Hoʻohana nui ʻia i ka PE, PVCChemicalbook, PP, PS, PC, polypropylene fiber a resinate resin a me nā mea ʻē aʻe. Hiki ke hoʻohana ʻia no nā mea hoʻopili e like me nā pahu plastik a me nā pahu pahu meaʻai, e hāʻawi ana iā lākou i kahi hopena stabilization māmā.
