Hiki i ka UV327 ke komo ikaika i ke kukui ultraviolet 300-400nm, ke kūpaʻa kemika maikaʻi, ka haʻahaʻa haʻahaʻa, ka hoʻohālikelike maikaʻi me ka polyolefin, haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, nonflammable, ʻaʻohe corrosion, kūpaʻa mālama maikaʻi, a me ka synergy nui me DLTDP (PS800). He kūpono loa ia no nā polymers i maʻa loa i ka radiation ultraviolet lōʻihi (e laʻa, polyimidites, polyphenyl sulfide) a me nā noi e koi ana i ka haʻahaʻa haʻahaʻa i ka lōʻihi hawewe ultraviolet radiation (e laʻa, ka lens optical).
Hoʻohana nui ʻia ia i ka polyvinyl chloride, polystyrene, unsaturated resin, polyurethane, polymethyl methacrylate, polyethylene, ABS resin, polypropylene fiber, pena, kala kala, adhesives a me nā polymers ʻē aʻe a me nā māla ʻē aʻe.
Hoʻopili ʻia i 20 a i ʻole 25 Kg / pahu pahu. A i ʻole i hoʻopaʻa ʻia e like me nā koi o nā mea kūʻai aku.
E mālama i kahi maloʻo a maloʻo; 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:
