O le photostabilizer UV770 o se mamafa molecular mamafa taofia amine photostabilizer, o loʻo i ai uiga o le fetaui lelei, volatility maualalo, dispersion lelei, feololo maualalo, mautu vevela lelei ma mautu opitika maualuga, ma e le mitiia le malamalama vaaia ma e le aafia ai le lanu. Mo le maualuga ma le mafiafia vaega o le fusi vaapiapi, faʻapipiʻiina, o loʻo i ai le photostability sili ona lelei. Faatasi ai ma le maualuga mole mole mamafa moli stabilizer ma ultraviolet absorber, o le aafiaga synergistic e taua.
E faʻatatau i: polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, polyvinyl chloride vaivai, polyurethane, polyformaldehyde ma polyamides, faʻapipiʻi ma faʻamaufaʻailoga ma isi.
Fautuaina aofaiga faaopoopo: masani 0.05-0.60%. O su'ega talafeagai e tatau ona fa'aoga e iloa ai le aofa'i talafeagai e fa'aopoopo i le fa'aoga fa'apitoa.
Faʻapipiʻi i le 25 Kg / pusa. Poʻo faʻapipiʻiina e tusa ai ma manaʻoga o tagata faʻatau.
Teu i totonu o se nofoaga malulu, matutu ma fa'afefe; aloese mai le susulu o le la.
Fa'amolemole fa'afeso'ota'i matou mo so'o se pepa fa'atatau.
New Venture Enterprise e fa'amaoni i le tu'uina atu o le HALS maualuga e fa'afetaui ai mana'oga eseese o nei alamanuia, fa'auluina le fa'afouga ma le fa'atumauina i le atina'eina o oloa, fa'amolemole fa'afeso'ota'i matou:
