E mafai e le UV327 ona faʻafefe malosi le malamalama ultraviolet 300-400nm, faʻamautu vailaʻau lelei, maualalo le faʻaogaina, fetaui lelei ma le polyolefin, maualalo le faʻafefe, maualalo oona, leai se afi, leai se pala, lelei le teuina, ma le fesoʻotaʻiga taua ma le DLTDP (PS800). E sili ona fetaui mo polymers e matua maaleale i faʻavelaina ultraviolet umi galu umi (faʻataʻitaʻiga, polyimidites, polyphenyl sulfide) ma faʻaoga e manaʻomia ai le maualalo o le transmittance i le umi o le galu o le ultraviolet radiation (faʻataʻitaʻiga, tioata mata).
E masani ona faʻaaogaina i le polyvinyl chloride, polystyrene, resin unsaturated, polyurethane, polymethyl methacrylate, polyethylene, ABS resin, fiber polypropylene, vali, vali lanu, faʻapipiʻi ma isi polymers ma le tele o isi fanua.
Faʻapipiʻi i le 20 poʻo le 25 Kg / pusa. Poʻo faʻapipiʻiina e tusa ai ma manaʻoga o tagata faʻatau.
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:
