ʻO UV326 he UV absorber o 300-400nm, me ka hopena stabilization māmā maikaʻi, hoʻololi i ke kukui ultraviolet i ka ikehu wela ma o ka hana photochemical; ʻoi aku ka maikaʻi o ka hoʻopili ʻana o ka pahu lōʻihi i ka huahana, kūpono maikaʻi me ka polyolefin, haʻahaʻa volatilization a me ka pale ʻana i ka ionization phenol; maikaʻi ke kūpaʻa alkaline ka huahana a ʻaʻole e hoʻololi i ke kala ma muli o nā metala. Ma muli o kona kiʻekiʻe ionization mau, metala maloʻo 'elele, catalyst ma kona haʻahaʻa mana; i nā huahana waho, hiki ke hoʻohana me ka phenolic antioxidant a me ka phosphite antioxidant.
Hoʻohana nui ia i ka polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin a pēlā aku.
Ka nui i manaʻo ʻia: 0.1% -1.0%, ua hoʻoholo ʻia ka nui kikoʻī e like me ka hoʻāʻo noi noi mea kūʻai aku.
Hoʻopili ʻia i 20 a i ʻole 25 Kg / pahu pahu.
E mālama i kahi maloʻo, maloʻo a me ka makani; pale pololei i ka lā.
E ʻoluʻolu e kelepona mai iā mākou no nā palapala pili.
Hoʻolaʻa ʻia ʻo New Venture Enterprise i ka hoʻolako ʻana i nā stabilizer kukui kiʻekiʻe e hoʻokō i nā pono like ʻole o kēia mau ʻoihana, e hoʻokau i ka hana hou a me ka hoʻomau i ka hoʻomohala ʻana i nā huahana, e ʻoluʻolu e kelepona iā mākou:
