UV326 o se UV absorber o le 300-400nm, faʻatasi ai ma le lelei o le faʻamautuina o le malamalama, faʻaliliuina le malamalama ultraviolet i le vevela malosi e ala i gaioiga photochemical; o le oloa e sili atu ona aoga le faʻaogaina o le fusi umi, fetaui lelei ma le polyolefin, maualalo le faʻaogaina ma le faʻafefe o le phenol ionization; o le oloa e lelei le alkaline tetee ma o le a le mafua ai suiga lanu ona o metals. Ona o lona maualuga ionization faifai pea, uʻamea faʻamago sui, catalyst i luga o lona aafiaga maualalo; i oloa i fafo, e mafai ona faʻaaogaina i le phenolic antioxidant ma le phosphite antioxidant.
E masani ona faʻaaogaina i le polyvinyl chloride, polystyrene, resin unsaturated, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin ma isi.
Fautuaina le aofaʻi: 0.1% -1.0%, o le aofaʻi faʻapitoa e fuafua e tusa ai ma le suʻega talosaga a le tagata faʻatau
Faʻapipiʻi i le 20 poʻo le 25 Kg / pusa.
Teu i totonu o se nofoaga malulu, mago ma fa'alili; aloese mai le susulu o le la.
Fa'amolemole fa'afeso'ota'i matou mo so'o se pepa fa'atatau.
New Venture Enterprise ua faʻamaoni i le tuʻuina atu o faʻamautu malamalama maualuga e faʻafetaui ai manaʻoga eseese o nei pisinisi, faʻamalosia le faʻafouina ma le faʻaauau i le atinaʻeina o oloa, faʻamolemole faʻafesoʻotaʻi matou:
