Hoʻokumu mua ʻia ʻo UV 312 e BASF.ʻO ia ka Ethanediamide, N-(2-ethoxyphenyl)-N'-(2-ethylphenyl) papa.

Hana ia ma ke ʻano he UV absorber no ka papa oxanilide.Hiki i ka UV-312 ke hāʻawi i ke kūpaʻa māmā maikaʻi loa i nā plastics a me nā substrates organik ʻē aʻe.Loaʻa iā ia ka UV absorption ikaika.No nā substrate he nui, hōʻike ia i ka hoʻohālikelike maikaʻi loa me ka volatility haʻahaʻa loa.

Hiki i ka UV 312 ke pale i nā substrate mai ka radiation UV a kōkua i nā polymers e hoʻomau i ke ʻano kumu a me ka kūpaʻa kino.

I ka ʻōlelo o ke kaʻina hana, ʻaʻole ia e hōʻike i ka hopena i ke kala a me ka ʻike o ka substrate polymer.Hiki ke hoʻohuiʻia me nā mea hoʻonani optical a kūpono i nā polyesters, PVC plastisol, polyurethanes, polyamides, polymethylmethacrylate, polybutyleneterephtalate, polycarbonates a me cellulose esters.

Manaʻo pinepine mākou no ka PVC a me nā polyesters paʻa a maʻalahi.Ma waena o 0.10 a me 1.0% i manaʻo ʻia o UV 312, ma muli o nā polymers a me ka hoʻohana hope.

Hiki iā Qingdao Topwell Chemical ke hana a hāʻawi i ka UV 312. Inā he pono kāu, hauʻoli mākou i ka loaʻa ʻana o kāu leka uila.
