UV 328 O se 290-400nm UV absorber ma lelei malamalama stabilization aafiaga-e ala i photochemistry; o le oloa e malosi le faʻaaogaina o le malamalama ultraviolet, maualalo le lanu muamua i luga o le lanu oloa, faigofie ona solu i le plasticizer ma le monomer system, maualalo le faʻaogaina, ma e lelei le fetaui ma le tele o mea faʻavae; i oloa i fafo, e mafai ona faaaogaina ma phenolic antioxidant ma phosphate ester antioxidantand taofia amine photostabilizer.
E masani ona faʻaaogaina i polyolefin, PVC, HDPE, styrene tasi ma copolymer, ABS, polymer acrylic, polyester unsaturated, polythermoplastic polyamine, susu faʻamalolo polyurethane, polyacetal, PVB (polyvinyl butyaldehyde), epoxy ma polyurethane lua-vaega faiga, ava malosi ma thermosetting acrylic faiga vali maneta; faʻaaogaina foʻi i taʻavale taʻavale, faʻapipiʻi fale gaosi oloa, faʻapipiʻi laupapa.
Faʻaopoopo le aofaʻi: 1.0-3.0%, o le aofaʻi faʻaopoopo faʻapitoa e fuafuaina e tusa ai ma le suʻega talosaga a le tagata faʻatau.
Faʻapipiʻi i le 20Kg/25Kg kraft taga pepa poʻo le pusa.
Aloese mai le susulu o le la, malamalama maualuga, susu, ma faʻamautu malamalama o loʻo i ai elemene sulfur poʻo halogen. E manaʻomia le teuina i totonu o faʻamaufaʻailoga, mago ma mamao ese mai le malamalama.
