Fa'atatauga

O le UV-3638 o le mamafa mole mole maualuga, maualalo le vaʻaia, faʻaleagaina le lanu. E sili ona talafeagai mo le alamanuia opitika e manaʻomia le lanu transmittance, e pei o PET, PC tioata mea mata, malamalama diffuser o backlit vai tioata faʻaaliga masini, ma isi. Uv-3638 e maua ai le malosi tele ma le lautele UV absorption, colorless filogia. O le UV-3638 e fetaui lelei mo polyester thermoplastic, nylon, ma fale puipui faʻatasi ai ma le maualuga o le vevela o le gaosiga ma manaʻoga faʻapitoa mo le faʻaogaina o le UV.
