Isicelo

I-UV-3638 isisindo samangqamuzana aphezulu, ukuguquguquka okuphansi, ukungcola okungenambala. Ifaneleka ngokukhethekile imboni yokubona edinga umbala wokudlulisa, njenge-PET, PC optical material lens, light diffuser of backlit liquid crystal display devices, njll. I-Uv-3638 inikeza ukumuncwa okunamandla kakhulu nokubanzi kwe-UV, ukungcola okungenambala. I-UV-3638 ilungele i-thermoplastic polyester, inayiloni, nezimboni zokuvikela ezinamazinga okushisa aphezulu okucubungula kanye nezidingo eziqinile zokumuncwa kwe-UV.
