Fa'aaoga
O lenei oloa o se mea e fa'amautu ai le malamalama ma lelei lona fa'atinoga, e mafai ona mitiia le ave o le UV o le 240-340 nm wavelength fa'atasi ai ma uiga o lanu malamalama, e le oona, fetaui lelei, faigofie ona gaoioi, faigofie ona fa'agaoioia ma isi mea. E mafai ona puipuia le polymer i lona tulaga maualuga, fesoasoani e fa'aitiitia le lanu. E mafai fo'i ona fa'atuai le samasama ma fa'alavelaveina ai le leiloa o lona galuega fa'aletino. E fa'aaogaina lautele i le PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate ma isi mea. E le gata i lea, e iai sona aafiaga lelei i le fa'amagoina o le phenol aldehyde, varnish o le alcohol ma le acname, polyurethane, acrylate, expoxnamee ma isi mea.
