UV absorber
I raro i te ra o te ra me te korikori, ko nga kirihou me etahi atu mea polymer ka uru ki te tauhohenga o te waikura aunoa i raro i te mahi a nga hihi ultraviolet, e arai ana ki te paheketanga o nga polymers me te paheketanga o te ahua me nga taonga miihini.Whai muri i te taapiri o te kaihoroi ultraviolet, ka taea te tango i nga hihi ultraviolet kaha nui ka huri hei kaha kino kia tukuna, kia pau ranei.Na te rereke o nga momo polymers, he rereke ano nga roangaru ultraviolet e whakaheke ana.Ka taea e nga kaihoroi ultraviolet rereke te tango i nga hihi ultraviolet me nga roangaru rereke.I te wa e whakamahi ana, me kowhiria nga kaihoroi ultraviolet kia rite ki nga momo polymers.
Ka taea te wehewehea nga kaihoroi UV ki nga momo e whai ake nei i runga i o raatau hanganga matū: salicylates, benzones, benzotriazoles, acrylonitrile whakakapi, triazine me etahi atu.
