Tono

Ko te UV-1200, he mea mimiti UV, he whakakapinga mō te UV-531 me te UV-9. Kāore he paitini o tēnei hua, kāore e mura, kāore e pahū, kāore e waikura, he pai te pumau o te rokiroki, ka taea te mimiti i te mārama ultraviolet 270-340nm. Ka ārai te pukapuka matū i te koroheketanga o te whakaahua, te pakaru me te pakarukaru o ngā rauemi polymer, ā, ka roa ake te ora o te rauemi. Nā tōna mahi pai, he whānuitia te whakamahinga i roto i te polyethylene, te polypropylene, te acrylic, ngā momo paninga kounga teitei me ngā peita motuka i tāwāhi.
