UV326 Ko te UV absorber o 300-400nm, ki te pai whakapūmautanga marama pānga, tahuri te marama ultraviolet ki pūngao wera i roto i te mahi photochemical; Ko te hua he pai ake te whakauru o te roopu roa, te pai o te hototahi ki te polyolefin, te whakaheke iti me te aukati i te phenol ionization; he pai te parenga kawakore o te hua, a, kaore e puta ke te rereke o te tae na nga konganuku. Nā ki tona ionization tiketike tonu, whakarewa whakamaroke kaihoko, whakakōkī i runga i tona mana iti; i roto i nga hua o waho, ka taea te whakamahi me te antioxidant phenolic me te antioxidant phosphite.
Kei te whakamahia te nuinga i roto i te polyvinyl chloride, te polystyrene, te kapia haunga, te polycarbonate, te polymethyl methacrylate, te polyethylene, te ABS resin, te epoxy resin me etahi atu.
Te nui e manakohia ana: 0.1% -1.0%, ka whakatauhia te moni motuhake kia rite ki te whakamatautau tono a te kaihoko
Kikī i roto i te 20 ranei 25 Kg / kātene.
Whakaorangia ki tetahi waahi makariri, maroke me te hau; karohia te ra tika.
