Isicelo

I-Absorbent ye-UV-UV-1200 ithatha indawo ye-UV-531 kunye ne-UV-9. Imveliso ayinayo ityhefu, ayinakutsha, ayinakuqhushumba, ayinakugqwala, ukuzinza kakuhle kokugcinwa, inokuthatha i-270-340nm ukukhanya kwe-ultraviolet, i-Chemicalbook ukukhusela i-photoaging, i-crack and brittle polymer materials, yandisa kakhulu ubomi benkonzo yezinto eziphathekayo. . Ngenxa yokusebenza kwayo okugqwesileyo, isetyenziswa kakhulu kwi-polyethylene, i-polypropylene, i-acrylic, i-coatings ezahlukeneyo zodidi oluphezulu kunye neepeyinti zemoto phesheya.
