Fa'aoga
O lenei oloa o se faʻamalama malamalama ma le lelei o le faʻatinoga, e mafai ona faʻaaogaina le UV radiation o le 240-340 nm wavelength ma uiga o le lanu malamalama, nontoxic, fetaui lelei, laʻititi laʻititi, faigofie gaioiga ma isi. E mafai ona puipuia le polymer i lona maualuga maualuga. , fesoasoani e faʻaitiitia le lanu. E mafai fo'i ona fa'atuai le samasama ma fa'alavelaveina le leiloa o lona tino. O loʻo faʻaaogaina lautele i PE, PVC, PP, PS, PC tioata faʻaola, polypropylene fiber, ethylene-vinyl acetate ma isi. E le gata i lea, e lelei tele le malamalama-mautu aafiaga i le faʻamagoina o le phenol aldehyde, varnish o le ava malosi ma le acname, polyurethane, acrylate , expoxnamee ma isi.
