ʻO kā mākou huahana, UV absorber 328, he hydroxyphenyl benzotriazole-class UV absorber e hoʻopaʻa pono i ka pāhawewe UV ma ka laulā o 300-400nm, ʻoiai e hoʻemi ana i ka absorption ma ka laulā māmā ʻike.
He pauka melemele māmā me kahi helu heheʻe o 80-88 degere, flash point o 229 degere, density o 1.17g/cm³, a me ka mahu puʻe o 4.7E-6pa. Me ka molecular formula o C22H29ON3 a me ka molecular weight of 351.5, hiki i kā mākou UV absorber 328 ke pale aku i nā polymers a me nā puaʻa organik mai ka radiation UV, e mālama ana i ke ʻano kumu a me nā waiwai mechanical o nā huahana plastik, nā kiʻiʻoniʻoni, nā pepa, nā fiber, a me nā mea ʻē aʻe i hoʻohana ʻia ma waho.
ʻO kā mākou huahana he mea hoʻoponopono māmā maikaʻi no nā plastics a me nā mea kūlohelohe ʻē aʻe. Loaʻa iā ia nā mea hiki ke hoʻoheheʻe ʻia, ʻaʻohe waihoʻoluʻu a ʻaʻole hoʻohaumia ʻia, kūpono me nā ʻano mea like ʻole, hiki ke hoʻoheheʻe maikaʻi i nā plasticizers a me nā monomers a haʻahaʻa i ka volatility. Aia ka kiʻekiʻe absorption peak ma 306 a me 347μm.
Ma ke ʻano holoʻokoʻa, hāʻawi kā mākou UV absorber 328 i ka pale maikaʻi loa mai ka radiation UV ʻino ʻoiai e mālama ana i nā waiwai aesthetic a me nā waiwai o nā mea plastik a me nā mea kūlohelohe.
