Ka taea e te UV327 te kaha te whakauru i te rama ultraviolet 300-400nm, te pai o te matū matū, te iti o te rereketanga, te pai o te hototahi ki te polyolefin, te iti o te ahua, te iti o te paitini, te kore e pupuhi, te kore e pakaru, te pai o te rokiroki, me te mahi tahi me te DLTDP (PS800). He mea tino pai mo nga polymers e tino tairongo ana ki te radiation ultraviolet roangaru roa (hei tauira, polyimidites, polyphenyl sulfide) me nga tono e hiahia ana kia iti te tuku ki te radiation ultraviolet roangaru roa (hei tauira, te arotahi whatu).
Kei te whakamahia te nuinga i roto i te polyvinyl chloride, te polystyrene, te kapia haunga, te polyurethane, te polymethyl methacrylate, te polyethylene, te resin ABS, te muka polypropylene, te peita, te kaihoko tae, te whakapiri me etahi atu polymers me te maha atu o nga mara.
Kikī i roto i te 20 ranei 25 Kg / kātene. Kikii ranei kia rite ki nga whakaritenga a nga kaihoko.
Whakaorangia ki tetahi waahi makariri, maroke me te hau; karohia te ra tika.
